450k$ for a part-time professor job in China?
This smells bad.
In America, part-time professors have a rough time, often teaching at several different institutions to cobble together enough money to pay the rent. And they don’t have any job security or benefits.
This is more akin to Hunter Biden, who had no special expertise in petroleum, finance, nor corporate governance, getting paid $1 million a year as a Burisma board member.
