 ### 重要的优化规则

@ran-huang FYI. The file name of the EN version is blocklist-control-plan.md, added in pingcap/docs#3043. I think we can keep the current Chinese file name now, because it's consistent with words in the body.

Got it. Thanks!

blacklist-control-plan.md

-5. 重新观察执行计划，`<` 和 `>` 表达式又可以重新被下推到 TiKV Coprocessor。
+5. 重新观察执行计划，可以看到只有 `>` 表达式被重新下推到 TiKV Coprocessor，`<` 表达式仍然被禁用下推。


@lzmhhh123 FYI. I've confirmed it with @winoros.
