I am still using MKII to do Chinese typesetting.
As I mentioned before, User should use this in their source files to
produce correct spaces between the chinese characters and english
中文 English 中文
which is quite annoying.
In order to remove this constraint,
here is what I have found out:
Uncomment line 248 and line 267 of font-chi.tex will do.

This patch works pretty good on most of the cases if you use 中文 English 中文.
however, 中文English中文 makes no space between chinese and English.
and changing the \chinesesurroundskip will only affect the space after English.
But it works now. I hope this information helpful.
Maybe ConTeXt experts can make more improvements in the future and
test from ConTeXt users are helpful.
