if a TA is not a local in your county, she will probably run off to
Yuncheng every weekend leaving you on your tod in the county.

Youth in China spend every second from the ages of 5 to 23 studying, sleeping, or addicted to their smartphone.

Thus your assistant will have zero practical knowledge of anything that is not within 100 metres of her home in her village, her jr. middle school, her middle school, and her university. They have no working practical knowledge of their own town, let alone any town a few kms from where they live. Anything 30 kms distant may as well be in another galaxy.

When she is assigned to you in September, a few weeks after obtaining her degree, she will be completely incapable of assisting you in finding the most simple things - a dry cleaner, a hardware store, a motorcycle dealer. She won't know what the concept behind the words you are saying means, even if she translates it. She will do what you do, which is to walk down the street and look in the stores with the added benefit that she can ask the locals where such-and-such store is located.

They do not know anything, about any practical subject. Beyond useless.

She will be berated in the street whenever she assists you, so she won't want to accompany
you. Passers-by will probably call her a traitor or a whore even in Yuncheng City.

...so just imagine the treatment in smaller towns that dot the Yuncheng Valley.

Two TAs walking with me, the first merchant we saw made a slur, they literally stopped walking that instant, 90 degree left hand turn, went to the curb, and stood under a tree and waited for me to walk away.

This is just one of the uncountable ways that the Yuncheng Valley/City/County is off the charts xenophobic, racist, hostile to foreigners, and oh-so "Traditional Chinese Culture and Values".

If you want to experience this, we warned you. Good story to tell, I suppose.
