Generally speaking, the English level of Chinese university students is crap.

Every Chinese university student that I have every taught can read and write English in a manner vastly superior to your ability to read and write Chinese.

In your parlance: generally speaking, the Chinese level of all FTs in China is crap.

Although my spoken Chinese language ability is intermediate level, I too cannot read or write Chinese.

I do not, however, need to compensate for my own poor Chinese by denigrating my students or their parents.
