If we think from SEO perspective its not good to have backlinks from non english blog to an English Blog Atleast not from china
In case you are merely looking to assemble backlinks doesn't necessarily really make any difference what words the websites are usually in, post about of which English-language forum/blog/article site which has a web page link inside your autosignature, it really is one way link Google can count number along with there is not any motive you can't work with your own personal words for the reason that point text, it isn't really best but it really is OK.
Links from other blog languages will help to rank higher in those countries. It will not harm your ranking if are quality backlinks.
Would be better to have them same language, however, if you want to rank higher where those languages are used, then this is a very good strategy.
