I see nothing wrong with telling lies to make money, that's how things work in this country!

Unfortunately, there are many unprincipled foreigners like you here on the mainland of China operating just as you are, and what's the worst of it, cheating any other westerner whenever they get the chance. For example, some old China hands borrow money from easily duped foreign teachers without the slightest intention of ever repaying their debts. Then double measures of Jack Daniels are swallowed in abundance. Disgraceful!
