Indicative reading, especially:

Living in China, where the rule-of-law doesn’t exist, means everyone has to look out for their own interest. It also means people have little or no respect for laws.

Confucianism and rule of law can never mix, when you have things such as verbal agreements and not honouring contracts, despicable!
