As long as he does not cheat Beida, it is fine.
If Beida want to give him more compensdation,
it is Beida's problem. It would be very stupid of
Tian to refuse. When an employment candidate seeks
employment with an employer, he always try to
maximize his salaries. If the employer want to
pay somewone who does one hour's work with 10 hours'
pay, there is nothing wrong with employees accetping
it as long as everything is told truthly beforehand.
