My daughter is a human resources specialist at a oil company parts manufacturer. She said that they were having to conduct an investigation into this young Chinese man than was hired as in an engineering position. He was having a hard time getting proficient in his assigned duties and was ultimately let go.

He filed a complaint and returned the day of his hearing with his whole family which some came all the way from China to attend. He acknowledged his difficulties but complained that he had paid another engineer money to work with him after hours to make him more proficient and he wanted his money back. That opened a whole other can of worms.

Evidently paying some one to tutor you on your job assignments is perfectly accepted in China.
