Job Advice for Pursuing a Tenure-Track Position in the U.S. (Postdoc in the U.S., Teaching-track/lecturer in the U.S., Tenure-track abroad)
In many fields and countries, it's rare to get a tenure-track position right after a PhD.  Generally speaking, if you want to go into tenure-track academia, a strong post-doc or two (or three depending on the field), with good publications is an asset, though it is also good to build up a teaching dossier.  I suspect the post-doc would allow you to be a more productive researcher than a starting faculty in the short term, though tenure-track in China probably has other advantages.
