I once heard the story of Li Ka-shing, the richest Chinese in the world: once after a banquet in Li Ka-shing, when I went out of the hotel and reached for a handkerchief from my pocket, a Hong Kong dollar copper coin fell out and rolled into a ditch. When Mr. Li tried to pick up the copper coin, the hotel waiter hurried forward, picked up the copper coin, wiped it clean and returned it to Mr. Li. Li Ka-shing recovered the copper coins, opened his wallet and took out one hundred Hong Kong dollars. Thank you for your help. Mr. Li got back a copper coin, but gave a tip of 100 yuan.

For this story, Mr. Li's own explanation is that every dollar is useful and should not be wasted casually. He wants to get the copper coins back, so that every dollar can play its due value. It is everyone's courtesy to thank others for their services. He gave a tip of 100 yuan, which was his heart to others. These are two things. He didn't spend 100 yuan on a copper coin.

"Kindness and cleverness" is another attitude of Zheng Shihua, president of Taiwan Province He Kang Securities Group. Zheng Shihua's father taught Zheng Shihua that as long as these eight words were fulfilled, his career would be successful. And these eight words also confirm the basic logic of Li Ka-shing's life.

Zheng Shihua promised to do things actuarially in every link, maximize the benefits during the period, and earn the maximum benefits with the least money. But being a man is not like this. Be as lenient and kind as possible to everyone, so as to have a good relationship.
