A poem in which good deeds should be remembered.

"But knowing and doing good, not asking about the future" was written by Feng Dao. His being an official violated the principle of "loyalty, honesty and shame" advocated by literati, so he was later criticized. If we only consider people's livelihood, Feng Dao is a good official who prays for the people and is willing to serve them. But as a courtier with Confucian education, his tactfulness and opportunism violated the way of monarch and minister, which was the biggest stain in his life.

Feng Daoyin was born in the Tang Dynasty. During the Five Dynasties, he assisted ten kings, held important positions for many times, and even served as prime minister of the Five Dynasties. Later generations even sarcastically said that he could not be a prime minister. Being in the era of political chaos like the Five Dynasties, being able to stay out of the way without falling from the position of a senior official can not only show Feng Dao's political talent, but also show that he is very cautious and good at catering to both sides.

After the death of Ming Zong in the late Tang Dynasty, Feng Dao's forbearance and ambition were exposed. He gave up his promise to trust an orphan and occupied an important position by supporting the rebellious king. He first supported Li Congke's rebellion to seize the throne of Mingzong in the later Tang Dynasty and was awarded the post of Shu Ren. Then he abandoned the last words of Han Gaozu at the end of Jin Dynasty and made his adopted son king. When the late Jin Dynasty was overthrown, Feng Dao won high positions repeatedly with his clever words.

In the post-Zhou Shizong period, Feng Daocai was no longer one of the three fairs, but was sent to repair the mausoleum. "But knowing to do good, Mo Wen has a future." It is to persuade people to just know how to do well in the present and not to think about what will happen in the future. This is in line with the image of Feng Dao, who only cares about the immediate interests to rise step by step. He will benefit the people and speculate everywhere to occupy a high position, but he never cares what future generations think of him.
