I'm guessing that that university has professors who are accent snobs. They feel qualified to judge English speakers' accents while at the same time having lousy English accents themselves.

I never said that his English skills were not up to par, nor did I assume that to be the case. Given that that 'university' had already signed a contract with him, I naturally assumed that the dean was satisfied with the applicant's paper qualifications and language background. Anyway, since I had posted, the OP has said the reason for the breach of contract by the 'university' was a big difference in the teaching methodology displayed by the OP during his 'critique' from what the 'university' was expecting. I think this is a pretext. Typical Chinese trickery, unique to Asian culture. As for demos, they can stick them up their ***es, as far as I'm concerned! Wuhan Poly deserves to be shunned by all Westerners!
