It is customary in China that children can't sleep in the East Room.

In the traditional customs of China, the East Room is usually regarded as the room of the owner or parents, and children are usually arranged to sleep in the Westinghouse. This arrangement may be based on the social hierarchy and Feng Shui belief at that time.

In ancient China, the concept of inferiority was deeply rooted in people's hearts, including the orientation and spatial distribution of houses. Dongzhai is located in the east, where the sun rises. It is regarded as a direction full of vitality and hope, so the East House is endowed with a distinguished position. Westinghouse is located in the west, where the sun goes down, which is considered to be a dark and backward direction, so Westinghouse is considered to be in a lower position. Under this concept, the master's bedroom is usually located in the East Room, while children or other family members are arranged in the Westinghouse.

In addition, from the perspective of feng shui belief, there are also some statements related to the orientation of Dongzhai and Westinghouse. For example, there is a saying that the East is an aristocratic party, suitable for placing valuables or letting nobles live; The west is a white tiger, representing evil and bad luck. Therefore, in the geomantic belief, Dong Zhai is also regarded as a noble residence.

In short, in the traditional customs of China, the East House is regarded as a distinguished residence, usually occupied by the owner or parents of the family; Westinghouse, on the other hand, is considered to be in a low position, usually occupied by children or other family members. This arrangement reflected the social hierarchy and geomantic belief at that time.
