这一次，换我说再见。 This time, it's my turn to say goodbye.

服务器与域名的开销，从来都不是负担。真正的挑战，是这份工作的价值常被轻视、贬低，甚至诋毁——最轻的便是：「程序员不值钱，实习生也能做。」却少有人知道，这些代码、尤其是机器学习算法的背后，是当前最前沿的学术探索；它们并非凭空而来，而是源自十五年前我博士阶段的研习与发表——涓滴成河，皆非一日之功。思量再三，我决定让它在这里，体面地停下。

The cost of servers and domains was never the burden. The real challenge is that the value of this work is often dismissed, belittled, and at times even disparaged — the mildest of it being: "programmers are cheap; any intern could do this." Few realize that behind this code, especially the machine learning, stands the frontier of academic inquiry — not conjured from thin air, but rooted in the study and publications of my doctoral years fifteen years ago. Drop by drop, a river forms; none of it was the work of a single day. And so, after much thought, I've decided to let it rest here — with dignity.

「海内存知己，天涯若比邻。」愿你的每一个研究，都有答案。江湖路远，后会有期。

"While a kindred heart remains, the ends of the earth are but next door." May every question you ask find its answer. The rivers and mountains are long — until we meet again.
