Review Comment:
   Maybe we shouldn't change vcs.xml file?

-The type can be declared using `CHAR(n)` where `n` is the number of code 
points. `n` must have a value between `1`
-and `2,147,483,647` (both inclusive). If no length is specified, `n` is equal 
to `1`.
+可以使用 `CHAR(n)` 声明该类型,其中n表示其长度,`n` 的取值范围为 `1` 到 `2,147,483,647` (包括两数在内) 
,如果没有指定`n` 的值,n 等于 1。 

Review Comment:
   其中 n 表示其长度
   
   There should be two spaces between Chinese characters and English characters.
