It appears that many of the Chinese rules currently in place are not functioning properly.
For example, I copied the text from the "Incorrect sentences that this rule can detect" line on this page: https://community.languagetool.org/rule/show/QIA1_QIA2?lang=zh&subId=2
今天要到国际会议中心， 恰 谈一笔户外广告的生意。
and pasted it into the textarea on languagetool.org with the language set to Chinese, and it claims that no errors were found.
I have tried this with a number of the rules on the rule list:
Some work, but many do not.
Is this something that can be fixed? Or are many of these rules currently invalid?
Unfortunately, I don't read Chinese, so I cannot provide more information than this.
