Liu Bang's victory comes from Cobb's modesty, his adoption of suggestions, his ability to judge the situation and his flexibility.

Xiang Yu's failure was due to improper employment, suspicion, stubbornness and lack of advice.

Therefore, we should sum up our experience and lessons: advice when unhappy is beneficial to action, and good medicine when painful is beneficial to disease. Be modest, not too arrogant. Be good at sizing up the situation. Be a man, be flexible. Don't doubt people, don't doubt people.
