The BGG database entry on Tichu needs copy editing. The English is really odd and part of the text is difficult to understand. I could fix the language issues, but I don't know anything about the game rules and so can't fix the comprehensibility problems.
It would probably be better to just rewrite it from scratch rather than edited. It's unfortunately written as super-condensed rules. But I didn't notice any egregious language issues. Can you quote the problem(s)?
Note that "More Information" does, in fact, have more information.
