Don't put fierce beasts down the mountain.
The so-called fierce beast down the mountain refers to the tiger. There has always been a saying in ancient folks that "a white tiger wears a hall, and the family breaks down." Although the white tiger is a beast in the eyes of the ancients, it can be said to be a beast among all animals. An ordinary tiger gives the impression that it is a very fierce animal. Generally speaking, human beings cannot compete with tigers without tools. Even with some tools, they may not be able to beat a tiger. No matter from the perspective of myth or reality, the tiger is a very ferocious animal. So, don't put these fierce beasts at home.
Don't wave your sword and weapons.
The basic principles of being a man in ancient times are six arts, namely, courtesy, music, shooting, imperial, calligraphy and number. Although with the rise of the imperial examination system, the requirements for those officials have gradually decreased, and they are not required to master the six skills of a gentleman. However, there are also many literati who are both civil and military in the past dynasties, and Li Bai is one of the famous poets and swordsman. Su Shi once described his hunting in "Hunting in Jiangchengzi Mizhou", which shows that he also knows something about "riding and shooting", so some people will use swords as decorations and keep them at home. But some people think it's not good. Why? The ancients believed in the golden mean, but these weapons symbolized struggle and ran counter to the way of life of those ancients. If swords and weapons are concentrated, domestic water will be destroyed.
Don't put antiques and jade articles of unknown origin.
The ancients liked to keep antiques or jade at home. They also made a special shelf to prevent these things from being damaged. Then why not put those of unknown origin? You should know that the ancients had the custom of being buried with others. Those antique jade articles may have been buried with the ancients decades, hundreds or even thousands of years ago. Many ancient people used jade to seal the seven orifices in order not to rot the corpse, but the profession of grave robbers has existed since ancient times. Therefore, for those antique jade articles of unknown origin, it is better not to start easily. After all, you have no way to know whether the sources of these things are irregular.
