The site has moved from Typecho to Hugo, which should make future maintenance easier. I hope it can go farther.

Early summer clears after rain, and I am twenty-one this year. Looking back, the road behind me has been bright and dim in turns, and all of it has made me who I am today; looking ahead, there are mountains and waters waiting for a future journey.

May the steady fire in my heart not be extinguished by the noise of the crowd; may there be clear light in my eyes, so I can still see the beauty of the world. When the wind comes, may I stand; when the rain falls, may I sing; may gain and loss not startle me, and may arrival and departure be met with calm.

Youth has its own will to reach the clouds; may I live up to the spring light and to myself. One year, one gift; one inch, one joy. This life is long, so I will keep walking and take care.

Happy birthday to me.

What is the reference point for time? When I was little, going from the county town to the countryside meant finding people and a vehicle several days in advance, and it felt like a very, very long trip. Now I find that riding there alone can take as little as half an hour, and even the bus arrives before long. I once thought the small road outside home had to be crossed by bike before it could reach the main road; now I realize it was only about the distance from a university dormitory to the campus gate.

In my memory, I began taking trains alone when I was thirteen. From Wuhan to Zhengzhou, in a sleeper berth, I slept in the middle bunk. I do not remember exactly how long it took. I only remember waking and sleeping by turns, looking at my phone, and eating the fruit plate my older brother bought for me. After arriving, I went to my uncle’s rented place on the top floor. In my memory, there were flowers, and there were stars.

Later, after starting university, I had to travel more than six hundred kilometers every half year. The high-speed train took more than four hours, and the ordinary train took twelve. One May Day holiday, I suddenly missed home and bought a lower sleeper berth to go back. That time actually felt fast. It was the only time in the past few years that I fell asleep on a sleeper train.

During this half year, I sometimes still travel alone, more than five hundred kilometers, eight or nine hours. The distance has not changed, yet it feels very far and hollow.

A couple of days ago I met up with friends and realized that none of us are actually very far apart, but meeting each other still often takes a year or half a year of waiting.

I remember when some people were only two or three meters away from me. Now the distance is an unknown number. Once in high school, during a break, I returned to school to read magazines and came across the phrase “one time, one meeting.” Without noticing it, I have already had a final meeting with many people: a classmate I happened to find in front of the classroom and chatted with for a few minutes; someone at a gathering who got drunk and told me we would stay in touch forever; an ordinary glance, a glimpse out of the corner of an eye; perhaps the farewell after we crossed mountains and rivers to meet; perhaps something I no longer remember, only that someone once told me, “Do not contact me.”

My hometown and old friends are getting farther and farther away from me, so far that the distance now has to be measured in years.

One time, one meeting; all who meet will part. A meeting is rare, and in this world it should be cherished.

2026 is almost here. The screen is still lit, and the wind outside the window is a little cold. The second hand on the watch moves one tick at a time, as if slowly shaving off the edges of this year, gnawing at time and at me, pushing me forward little by little.

Looking back on this year, my first reaction is not summary but surprise: I am still here. I cried at this time last year too, and the tears fell very seriously, as if I were wrestling with myself. I am quite sentimental, and quite stubborn.

I did many things this year. The blog was built from zero, and the pages took shape bit by bit; videos were edited one after another, and the images and rhythm slowly became smoother; knowledge was learned layer by layer, forgotten after learning, then learned again; with help from teachers and friends, I achieved some pretty good results. I also did not lose that drive for AI. I still want to stand a little farther forward, even if it only means looking once more or trying once more. Through crying again and again, I have also become stronger. Pain is a trial arranged specially for me; once I embrace it and turn it into part of myself, from then on I become a unique and stronger self, and I know where to go.

That does not mean there were no regrets. There were too many things, and I divided my time in a terrible mess. Several very important things were not finished, and some were simply missed. A friend once told me something I still remember: “Since you have recognized the problem, do not keep failing to change direction just because of inertia. Change your methods and actions quickly, and act right away.” This year I also argued for a long time with someone close to me. It is the thing I regret most, bar none.

This year I also met many people. New friends came, old friends stayed, and no one was lost. A small childhood wish was also made up for: I opened a Minecraft server, and with the person I first played with. More than ten years have passed, and we are still mining and building houses on the same map. Thinking about it, we are really quite amazing.

There was also one very long-held wish: I met an online friend I have known for almost ten years. We laughed loudly at the amusement park. Because you were beside me, I pressed down the safety bar and went on the pirate ship and into the haunted house. Courage sometimes does not suddenly grow out of nowhere; sometimes it is someone walking one step forward with you.

People live in ordinary society, and one tree alone cannot stand. Without family and friends, there would be no me today. Thank you for always tolerating me.

In the new year, may there be peace and joy. May the days contain small, scattered happiness, and also the strength to set out again at any time.

At the beginning of the year, I was really frantic trying to find some code for data analysis. Later I realized that the hard part was not the code itself, but that the code was too scattered, and much of it had been wrapped in commercialization that was expensive and opaque.

I had an idea then: to share all the things I used. That idea stayed buried deep in my heart, and recently it finally burst out.

After five days and five nights of grinding, XiLiSuite (溪狸 · 析理) was born. The name comes from “析理” and is transliterated as “溪狸.” I hope it is like a tabby cat by a data stream, picking up light and flowers, sorting the mess little by little, and finally letting the answer remain clear and visible even amid the noise.

To make it easier to get started, I also made a visual interface. It is currently an initial version and is still being improved. Everyone is welcome to try it, give suggestions, and help polish it: Project address: https://github.com/Rosetears520/XiLi

Current features include (continuously updated):

1. Data processing and statistical analysis: linear interpolation, annual averages, average annual growth rate, K-Means clustering, grouped processing and tests, and more
2. Image and text tools: image binarization (black-and-white conversion), document word segmentation, word cloud generation
3. NLP / topic modeling: LDA training and evaluation (perplexity/coherence), SnowNLP training and sentiment analysis

Today is the 403rd day of running the account “Rosetears,” and the 313th day of the blog with the same name. On this ordinary day, the Bilibili follower count finally reached 1,000, and the website is also close to 100,000 visitors.

I started this account more than a year ago for a very simple reason: to teach what I know to specific people; and, along the way, record the content and write it into blog posts, making it convenient for others and for my future self. Back then, I probably still carried a bit of youthful pride, always feeling that much knowledge was not actually complicated, yet had been packaged layer after layer into paid barriers. In my heart, the basic color of the internet should be sharing and mutual help.

Along the way, the people I teach have changed, and I have changed too. I gradually understood that “generating electricity with love” inevitably becomes difficult in reality. Money is both the highest threshold and the most realistic problem. So I enabled self-service support, but I still insist on keeping the content free. I hope that in the future I can find a balance between ideals and bread.

The time spent running this account has truly been happy, especially in the past half year. I am an emotional person, and I remember everyone’s help and support for a long time; even late at night, my eyes often grow wet because of that warmth.

Especially aw and Guagua, two friends who gave me unprecedented support and advice. I learned a lot, and they also helped me slowly gain a clearer direction for where the account should go next. Thank you also to everyone willing to stop and take a look. Because of you, I am more certain that I am becoming my true self, and doing what I truly want to do.

Sometimes I also feel lost: I do not know how to keep going, and sometimes I really cannot hold on. Maybe this really is a journey where collapse is allowed, but as long as you are still here, I want to walk a little farther and a little longer with this small site.

I hope both the account and the small site can last for a very long time. May we all do the same. I am truly very happy. Thank you, everyone.

I suppose I am a somewhat old-fashioned person. The things I use are often old objects long left behind by the times. For example, the most ancient single-blade razor. I know perfectly well that it has a hard temper and will cut me if I am careless, but I still cannot bear to replace it. Just like an hour after shaving, I looked in the mirror and found twelve tiny blood spots.

I also like writing letters. I remember the first letter I sent: I wrote traditional Chinese characters vertically, and my friend could not understand it at all. Later I sent over the translation, and they complained that I had not brought it out sooner. It was funny and happy.

Nowadays everyone is busy opening accounts on short-video platforms, but I prefer to slowly build my own blog and write down the days inch by inch. No one rushes me, no algorithm pushes me, and I speak at my own pace.

I do not have many friends, and some of the friendships are strange. My two closest friends are people I met online. The three of us have almost nothing in common, with a large age gap and wildly different interests. The only common point is probably that we are all human. Yet we can be happy together and help one another. And these three people who seem utterly unrelated have somehow stayed with each other for nearly ten years.

I also seem able to chat with almost anyone. I have no one I truly dislike, and no enemies either.

I am enthusiastic about new things too. When a new AI product comes out, I am always among the first to try it; then, from a pile of choices, I pick the one that suits me best and use it until it feels familiar and smooth. When I encounter a new product I think is good, I also support it with real money and write feedback seriously.

But I do yearn for a slow life and like a warm rhythm, while my schedule is always packed and anxiety often follows me.

I seem to have always been working hard to become a clearer version of myself, yet I often do not understand myself. It seems that I possess me, but cannot fully decide me.

A journey where both sides move toward each other is the one that matters!!!

Yesterday I went to Happy Valley with Dandan! The thrilling rides are still the fun ones: drop tower, roller coaster, pirate ship, and so on. Also, haunted houses are only fun when they have NPCs. You cannot play them too many times. If you play too much, you get desensitized and stop feeling anything.

After playing, we went to Haidilao for dinner. We have known each other for so many years, from ninth grade to senior year of university. We finally met in person!

Sigh. I have thought it through. In the future, when I should charge, I will charge… I will stop being such a pushover… I am actually quite short on money…

If I did not buy anything or add anything new, it would be okay. But improving the quality of the blog suddenly makes expenses exceed income. For example, wanting to buy a microphone and audio interface to improve video recording quality, testing and comparing the specific capabilities of large models, and so on all consume a lot of money and time… Sigh, it is really hard. But I also do not want to make articles paid-only, because many people still cannot afford that, and it would go against my original intention.

It got colder today, and it also snowed over at school. I started feeling sad. I miss home, wuwuwu. I want a warm place.

I am glad it helped you. Thank you very much for your support too! I am still an undergraduate right now. But my major is economics and management, so data analysis is used a lot in papers and reports; large models are my personal interest.

Keep going! I think the creator can definitely succeed, www. You solved my CCR problem. I also want to learn data-analysis tutorials. May I ask what you do for work? I think what you are making is excellent.

I migrated all of the website content to Alibaba Cloud! Operations success!!!

Hehe. Today Tangtang gave me a year of QQ Music membership. I am so happy!!!

Dandan also said he is coming to see me. Wuwuwu, I have known him for so many years. We said we would meet back in 2018, and now we are finally going to meet!!!

Ever since I built this website, I have felt that I have my own lonely island in the waves of the internet, and I can always take my own little boat here.

Sigh, I have had another disagreement with the girl I like… Girls are so complicated. How can I coax her properly…

Sigh. Sad. Data-analysis tutorials get little traffic; simply doing AI hot topics gets more traffic ＞﹏＜

On October 7, 2025, I changed the blog theme from JOE 再续前缘 to the handsome theme. I hope it can go very far, and that I can do the things I want to do.
