Answer: "Ten thoughts", that is, ten suggestions, can be summarized as "five precepts": "seeing desire" and "doing desire" to abstain from extravagance; The two precepts of "thinking about high risks" and "fearing overflow" are pride; Two abstinence rules, namely "have fun" and "worry about being lazy"; The two commandments of "fear of ignorance" and "fear of evil" are words that do not trust people; The two commandments "added by grace" and "added by punishment" are unfair.

The solution of this "ten thoughts" was put forward against the "ten forgetfulness" of Tang Taizong since the middle period of Zhenguan, which was the main problem that Tang Taizong had to solve at that time. Every thought in Ten Thoughts first describes the realistic problems that Emperor Taizong encountered under the current situation of "living in peace", and then puts forward the solutions to these problems. Wei Zhi's intention to closely link thoughts and actions here is profound. It turned out that from the middle of Zhenguan, Emperor Taizong advocated empty talk and was not pragmatic, which became more and more fierce. For example, in the eleventh year of Zhenguan, he visited Luoyang Palace, rowed on a green pond and saw the pavilions built by Emperor Yang Di who squandered people's fat and paste. He also commented, "(Emperor Yang Di) is so lucky that people can't stand it", "He filled the world with resentment and rebellion, and he died and ruined the country". It seems that he should take Sui as a mirror, but in the end he proudly said, "Today his palace is the best. "Another example is the selection of talents. Emperor Taizong has said it a thousand times, but there is no decent action. Wei Zhi's ministers criticized: "The country has been loyal to the monarch and virtuous, but it has been more than ten years. What a pity! "This is also true, this is true, this is not true. "How can we match our words with our deeds? Then you must always reflect on yourself, check yourself from all aspects, and get rid of your own problems, instead of empty talk. This is the spiritual essence of "Ten Thoughts". Finally, the author explains that to sum up the "Ten Thoughts", carry forward the "Nine Virtues" and select talents, the people don't have to "think hard", but the country can "rule from the arch." "Governing by bending the arch" is different from Laozi's "governing by doing nothing". It requires Emperor Taizong to "be prepared for danger in times of peace and refrain from extravagance and frugality", which is to seek treatment actively, rather than passively treating incurable diseases.
