How to leave only Chinese characters in a string?

Hello. I have the following problem. There is a string that has Latin and Chinese characters in UTF-8. How can I remove all Latin characters from a string and leave only Chinese characters?
Type regular : '/[x{3040}-x{312F}]/u'throws an error.
Thanks in advance to all who respond.
