From en.pinduoduo.com:

> Pinduoduo's core value is "本分" (Ben Fen). It is difficult to express it perfectly in English, but it essentially means to adhere firmly to one's own duties and principles. There are several layers of meaning here:

> Be honest and trustworthy;

> Discharge our own duties and responsibilities regardless of others' conduct;

> Never take advantage of others even when we are in a position to do so;

> Self-reflect and take responsibilities when problems arise instead of blaming others.

I guess the company's app developers never got the memo.
