在linkedin上可以联系国内的猎头，了解一下行情。一般来说，雇主对于适龄未育女士还是多少有些歧视的。

可以的

With your age, you should already have many years industry work experience in US, so should not be difficult to find a job in China (of course, depending on which city). I have a lot of friends constantly have recruiters from China reaching out to them for opportunities in China, such as team manager, leader etc.

楼主要做好思想准备，国内年龄歧视非常非常严重，基本过35，就开始歧视了
