Preface
A few days ago, I needed to log in to my QQ Mail, which required scanning a QR code with QQ. I opened the QQ app that hadn’t been launched for a long time, and there was a message sitting there from 20 days ago.
Body
A few days ago, I went back home for the Mid-Autumn Festival. There are no trains in my hometown, so I always have to take a bus when going home.
I don’t usually go home often. This time, I didn’t plan to go either, but on a whim, I decided to return to see my family.
Since I started boarding school early, I have fewer than 10 friends in my hometown. I never imagined I would run into an acquaintance on the way home.
Even less did I dare to think that after nearly 10 years without seeing each other, I could still be recognized at first glance.
And I certainly didn’t expect that if it weren’t for needing to log in to my email, I probably wouldn’t have opened QQ for several more months due to some other reason, and thus I likely would have missed this message.
If a user does not log in for more than one month, the system automatically deletes their unread messages. This means that if you haven’t logged into QQ for a long time, messages sent by others may be automatically cleared after one month (there is no official statement; this is based on patterns summarized from information circulating online).
Was it really such a coincidence? It was exactly such a coincidence! Any of the following conditions missing would make it impossible:
I went home for the Mid-Autumn Festival.
My friend also went home for the Mid-Autumn Festival.
My friend recognized me despite us not having seen each other for ten years.
My friend boldly sent a message (after all, mistaking someone for another person can be quite embarrassing).
I opened QQ—which I often don’t open for months—because I needed to scan a QR code to log in to my email, and received the message.
Life is truly wonderful. A series of coincidences happen one after another like this. This experience deeply moved me because the probability of this event occurring is so low that if someone else had told me about it, I definitely wouldn’t have believed it. After this incident, I couldn’t help but think that many things that happen in stories might have actually happened. Low-probability events ≠ impossible events. What reason do I have to doubt the authenticity of those low-probability events? Just because I haven’t seen them? Just because the probability is small enough?
Let’s keep a sense of awe for the unknown and miracles 
Postscript
Follow fate, cherish connections.
When I have free time in a few days, I’ll visit this friend in person. I’ll update then with details of our meeting.
