4. Keep promise and credibility

We must always keep promise and be credible. Two key factors to keep to be credible:

• First, tell the trust when asking for help. dishonest would harm one's reputation and the trust once had.  
• Second, to help others, one must have the capability to fulfill the promise.

It's important to help our friends the best we can, but it is more important to reject the request if you can't fulfill as this would hinder people from finding better opportunities. 

lastly, when helping, do not show superiority over others.
