Little People of Tang Dynasty

He was originally a nobody, but he became a beggar after traveling through time. He is neither a high-ranking official nor a rich second generation, so he has no right to be picky; He knows that in order to achieve his goal, force alone is not enough. The most important thing is to use your brain. He does all kinds of bad things, and he does it with peace of mind. Even having a hundred heads is not enough to squander, but he lives happily. He has the help of noble people, has excellent luck and opportunities, has a keen eye in difficult cases, and has countless heroes who are ready to die for him; He knows where he can be a great man, where he can thrive in the world of business, prosper in officialdom and temples, and be invincible on the battlefield; He understands when to be a coward, fulfills his mission and resolutely takes the opportunity to go into seclusion, to prevent the bird from disappearing and the rabbit to die, and to return to the happy life of a small person. With a clever mouth, is he just trying to show his poverty? No, truth is also false and false is also true. This is wisdom. What kind of imperial examinations should be taken and what kind of morality should be emphasized.
