According to the PSB, the westerner was too old to teach!

I have repeatedly heard many stories on this.

Ads online state 60 as the cutoff in many cases.

The law in China is 60 for teachers or 65 if management.

Yuncheng EV says that 65 is the cutoff.

Older Yuncheng IELTS teachers had to leave at age 71.

Many teachers in rural China are 65-75, but that was pre-2012. The law was always 65 then lowered to 60 for teachers, but pre-2012 all laws were loosely enforced, if at all. Again, all this changed in March.

But the new law is age 60 and no more teaching, so anyone 62, 65, etc, is too old.

The teacher in Yongji with the spouse is one such example.

It used to be that Guanxi and money could fix this, but that has all changed since March, 2015. These changes accrued beginning August, 2014, but have really gotten out of hand since everyone came back after Spring Festival.

Since it appears that this trend of tightening application of the rules will not abate, it seems likely that there is at least 7 more years of this to look forward to under current leadership. I would not want to ponder what is next. Registration cards for foreigners? Restrictions upon foreigners travel freedoms? Access to global internet completely shut off? Worse?

Since the internet is all but broken in China for outside communication (I am surprised this site is still reachable), again this started in August, 2014, and is now extreme, it seems clear to me that things will be getting worse and not better.

Thus the recommendation to leave.
