Hong Kong Marathon in 2026

I signed up for the half marathon and it took 2 hours, 16 minutes and 49 seconds. It's okay to run alongside others Don't stop, don't compare myself to others Um, the scenery is nice The shouts of the crowd are so noisy The advantage of staying in a hotel is that I can shower after running. My pants had white crystals on the waist and knees; I looked it up and it said that this is what happens when sweat evaporates. I packed my bags and took the high-speed train back to Shenzhen. The pain started as soon as I got home. My body wasn't used to the sudden increase in exercise, causing a lot of lactic acid to build up in my muscles. The symptoms were: muscle soreness. I was limping when I walked. Going up and down stairs was also difficult; going up was okay, but going down was painful. I could only go down one step at a time; if I went down too fast, I was afraid of falling. Others First. A beautiful woman On the subway from Victoria Park back to hotel I saw an elegant woman in a black dress and liked her very much. She was so beautiful that I felt ashamed of myself. She just quietly gazed out the subway window. I glanced at her once, then glanced again, not wanting to look any longer. What was she thinking? Sometimes, meeting such a beautiful woman is truly a wonderful thing. Second. Has my sensitivity to the suffering of others decreased, or am I refusing to feel it? On my subway home, something happened: A girl was squatting in the carriage. At first, I didn't pay attention until she stood up and suddenly knelt down, hitting her head on the floor. The sound was so loud it startled me; I thought she might be mentally unstable. Then, people around noticed something was wrong. A young man proactively helped her up, and someone offered her a seat. Only then did I see: her complexion was very poor, and she seemed listless. Afterwards, the young man talked to her, gave her water, and helped her off the subway. If I had noticed her situation earlier, perhaps she could have suffered less? But I didn't. Why? I've lived alone for too long and don't know how to interact with others. I often plan my life in a purely rational way, never considering my potential interactions with others. I hope this solitary lifestyle can change somewhat, so I don't have to shut others out of my heart. Not everyone you meet wants to hurt you.

参加26年香港马拉松

我报名了半程马拉松，用时2小时16分钟49秒。跟着别人跑也挺好别停下来，别和别人比嗯，风景不错人群的呐喊声好吵啊住酒店的好处就是跑完之后能洗澡。我的裤子腰部和膝盖部位都是白色结晶，查了资料说是汗液水分蒸发后就是白色的。收拾一下行李，就坐高铁回深圳了。到家后痛苦就开始了，身体并不适应突然增加的运动量，导致我的肌肉堆积了很多乳酸。表现就是：肌肉酸痛。走路时都是一瘸一瘸的。上下楼也不好受，上楼还好，下楼就很痛苦，只能一步一个台阶下，下得快了，担心会摔倒。其他一、美丽的女士在维多利亚公园回酒店的地铁上，看到了身着黑色裙子、有气质的女士，很喜欢。好看得让我自惭形秽。她只是静静地望着地铁窗外。我看了她一眼，没看够又看了一眼。她在想什么呢？有些时候，能够遇见这样美丽的女人，其实是很好的事情呀。二、我对他人痛苦的感受力下降了吗，还是拒绝感受呢坐地铁回家时，发生了一件事：一个姑娘蹲在车厢，一开始我没在意，直到她站起来然后突然跪下脑袋撞到地上。那声音大得吓我一跳，我以为她是不是精神不太正常。再然后，周围的人发现了异常，一个小哥主动上前把她扶起，有人给她让座，我才看到：她的脸色很差，整个人没什么精神。之后，那个小哥和她说话、喂她喝水，并扶她下了地铁。如果，我能早点注意到她的情况的话，或许她可以减少一些痛苦呢？只是我没有注意到。为什么呢？自己一个人生活太久了，不知道怎么和他人相处。很多时候一直用一种纯理性的方式去规划自己的生活，从来不去考虑自己可能和他人有什么交集。我希望这种孤僻的生活状态，可以改变一些，自己不必把别人挡在自己的心门之外。并不是你遇到的每个人都是想伤害你的人。

Run 7 kilometers, Jupiter at opposition

I worked eight hours of overtime yesterday, and didn't want to work any more in the evening because I felt unwell, so I went home and slept from 6 pm to 9 pm. Seeing photos of the starry sky on my WeChat Moments reminded me that I could observe the "Jupiter opposition" phenomenon. So, I put on warm clothes, went downstairs, walked to an open area in a nearby park, lay down on the ground, and held up my binoculars. At first, I couldn't find Jupiter, so I opened a star chart app and found that Jupiter was roughly in the northeast at that time. Through the binoculars, Jupiter appeared as a very bright dot, but because the magnification of the binoculars wasn't high, Jupiter's rings weren't very clear. I didn't fall asleep until after 2 AM this morning, and woke up after 8 AM. The sun was shining brightly outside, reaching the balcony, so I took out the blankets that hadn't been aired for a few days to dry. I was thinking about whether to go for a run. The reason I wanted to run is because of the marathon next week; if I don't run a long distance, I might not be able to finish the actual marathon. I set my fitness watch to 11 kilometers, but only ran 7 kilometers. My shoes started rubbing my feet while I was running, and when I took them off when I got home, I saw I had a blister on my foot :). I was constantly breathing heavily while running because I haven't run a long distance in a long time. Fortunately, I felt pretty good after the run, but my foot was still hurting because of the blister, so I could only walk a bit and then stop. While running, I listened to an episode of the podcast "Culture Limited" that talked about some things about Buddhism and mentioned many profound concepts that I don't quite understand yet, but I want to learn more about them.

跑步七公里，木星冲日

昨天加班了八小时，晚上不想继续加班因为觉得自己身体有些难受，就回家睡觉了，从六点睡到九点。看朋友圈有人发星空的照片，我才想到可以观测“木星冲日”的天象。于是，穿好保暖的衣服就下楼，走到附近公园的开阔处，躺在地上手举着双筒望远镜看，一开始没找到木星在哪里，于是打开一个能显示星图的app，找到木星那个时候大概在东北方向。望远镜看木星是一个很亮的圆点，由于望远镜的倍率不高，所以木星的圆环看不太清。今天凌晨两点多才睡，醒来已经八点多了。外面太阳真好呀，照到阳台上，把有几天没晒的被子拿出来晾晒。心里想着要不要跑步呢，之所以想跑是因为下周的马拉松，如果不跑一次长距离真正跑马拉松的时候可能会无法坚持下来。运动手表设定十一公里，最后只跑了七公里。因为跑着跑着鞋子磨脚，后面到家脱鞋一看，脚上已经磨了一个水泡:)。跑步的时候一直呼气吸气个不停，因为我很久没跑长距离了。好在跑完步状态还不错，就是脚因为水泡一直疼，只能走一段停一段。跑步的时候听了《文化有限》频道的一期播客，里面讲到了佛教的一些东西，提到很多深刻概念，我还不太懂，但是想要学习了解。

Teeth Cleaning

Back in early November, I was reading up on health stuff, dental health included. The advice was to get your teeth cleaned regularly—it gets rid of tartar and plaque, preventing all sorts of oral problems. Didn’t do much research for the clinic. Just did a quick search on WeChat and Amap and found Tongbu Dental. Booked an appointment for today two weeks ago at their Xixiang branch. Took almost 50 minutes to get there from my place. So yeah, based on that alone, won’t be going back there next time. They put this mask over your face, everything but your mouth, because that operating light is insanely bright and uncomfortable otherwise. Didn’t hurt much during the cleaning, just a bit of sensitivity in one spot. But I was pretty on edge the whole time, scared I’d suddenly get a shooting pain. Thankfully, that never happened. The Meituan group deal was only 68 yuan—felt almost too cheap. I’ve asked around, and my colleagues have paid two or three hundred. I’ll try somewhere else next time, test out different chains and see what the difference is.

洗牙

11月初的那段时间，在了解健康方面的知识，其中就有牙齿相关的内容。建议是每隔一段时间就洗一次牙，可以去除牙结石和牙菌斑，预防很多口腔疾病。找口腔医院的话没怎么调研，就是在微信和高德地图上搜了一下，找到了同步齿科。两周以前约的今天，在他们的西乡店。离我住的地方不近，花了50分钟左右才到。所以基于这一点，下次洗牙不会选择这个地方了。洗牙的时候会用一个面罩盖住除嘴以外的位置，因为无影灯光线太强，不盖的话人会不舒服。清洁的时候，我没觉得有很痛的地方，只是清洁到某个部位时有轻微的酸。不过，在过程中我到是挺紧张的，害怕自己突然牙痛。所幸这种事并没有发生。美团团购价只花了68块，觉得有些太便宜了，我问过同事，他们花两三百的都有。下次换一家看看，多尝试不同品牌的口腔医院，看看有什么区别。

Romeo and Juliet (musical)

I bought tickets for this show the day it went on pre-sale—two tickets in total, costing over a thousand yuan. I wanted to watch it with a girl, and even looked for someone online. Eventually, someone did watch it with me, but it wasn't at all like I'd imagined. Today, I want to say: finding someone you like is actually quite difficult. When the mother tells Juliet that she must marry, there are two real people upstairs, and downstairs, as if mirrored, two more people, hidden in the shadows. I think this is a representation of the inner world of the mother and Juliet. Expressing their inner struggles through physical performance is quite interesting. The dance of death runs throughout the play; it's a very special element. The shadow of death looms over it constantly, and the tragedy reaches its climax at the moment of death. I really liked the encore songs, and here are a few excerpts: Avoir 20 ans, c'est jusqu'au matin Being 20 means living until morning Avoir 20 ans, c'est gratter sur des guitares Being 20 means strumming guitars Refaire le monde même si ça change rien Reinventing the world even if it changes nothing Avoir 20 ans, c'est rêver tout haut Being 20 means dreaming out loud Nous, on n'a rien du tout We have absolutely nothing La vie devant nous Our whole lives ahead of us Avoir 20 ans, c'est trembler de peur Being 20 means trembling with fear D'oser aimer, d'ouvrir son cœur Of daring to love, of opening your heart Avoir 20 ans, c'est se mettre en colère Being 20 means getting angry Ne croire en rien mais attendre tout Believing in nothing but expecting everything Avoir 20 ans, c'est rêver tout haut Being 20 means dreaming out loud Let us all strive together.

罗密欧与朱丽叶 Roméo et Juliette (musical)

这部剧刚开始预售的那天，我就买了，而且买了两张，花了一千多。心里想找个女孩一块看，甚至还在网络中找人，最后的确有人和我一起看，只是全然没有了当时幻想的样子。在今天，我想说：找到一个喜欢的人，还是蛮难的。当母亲告诉朱丽叶，她必须嫁人时。楼上有真实的两人，楼下仿佛是镜像一般也有两人，处于暗中。我以为这是母亲和朱丽叶的内心的具象。通过动作表演来表达双方的内心挣扎，很是有趣。死神的舞蹈贯穿剧目始终，是个很特别的存在。死亡阴影一直笼罩在其中，一场悲剧在人死亡的那一刻达到剧情的高潮。返场曲目我很喜欢，摘录只言片语： Avoir 20 ans, c'est jusqu'au matin 二十当头，通宵悠游 Avoir 20 ans, c'est gratter sur des guitares 二十当头，抱起吉他胡弹乱奏 Refaire le monde même si ça change rien 想改变世界，可世界依旧 Avoir 20 ans, c'est rêver tout haut 二十当头，天真梦想云雾飘游 Nous, on n'a rien du tout 我们，一无所有 La vie devant nous 只有生活在前头 Avoir 20 ans, c'est trembler de peur 二十当头，彷徨无奈 D'oser aimer, d'ouvrir son cœur 谁敢为爱，敞开心怀 Avoir 20 ans, c'est se mettre en colère 二十当头，一腔愤慨 Ne croire en rien mais attendre tout 只信美梦，渴望期待 Avoir 20 ans, c'est rêver tout haut 二十当头，大声梦想与诸君共勉

Stargazing Diary 251105

Yesterday, almost twelve o'clock in the middle of the night just finished the supper, suddenly remembered that today has the largest full moon of the year, picked up a long unused telescope, came to the balcony. Seeing a lot of stars with a telescope, the weather is really good today. The moon was above my head, and the telescope was raised to look hard, but it was hard to shake, so I had to put down the telescope and look at the round moon. Think about something I don’t know so-called.
