Is the couplet on the gate on the left or on the right?

Usually the couplets of the gate are placed on the right side of the gate, and the couplets are placed on the left side of the gate. This is because China's traditional calligraphy, seal cutting and other art forms are written from right to left, so it is in line with the norms of traditional calligraphy to put the upper couplet on the right and the lower couplet on the left. However, there are some special circumstances, such as small doorway or complex building structure, and sometimes the position of couplets may be adjusted appropriately according to the actual situation.
