Buddhists in the Tang Dynasty pinned the guardian image of the lion on the stone lion, which can achieve the purpose of exorcising evil spirits in the town house. Moreover, due to the influence of some policies of Wu Zetian, Buddhism in the Tang Dynasty far surpassed that in the previous dynasty. At that time, it was widely popular in the north and south, so it gradually became a unified town house beast in the hearts of the public, and it also represented the desire of many people to pray for family peace.
As a native animal in China, tigers have always been loved by people, and people often hang tiger paintings indoors to ward off evil spirits. Even children have some tiger patterns on their clothes, but people are more afraid of tigers besides worshiping and loving them. Because tigers often ate people in ancient times, people thought tigers were fierce and didn't put them in front of the door.
Moreover, for China Feng Shui, the lion is yin and the tiger is yang, so generally speaking, the lion can not be placed indoors but can be placed outside the door to ward off evil spirits, while the tiger can only be placed indoors, not at the door.
As the king of our beasts, the tiger is not easy to be tamed, and the lioness has been tamed from the beginning, so people will certainly like the lion that is easy to tame, so it is more reasonable to regard it as a beast in the town house.
