Spatial sequence of layout China architectural art is mainly the art of group combination, and the connection, transition and transformation between groups constitute a rich spatial sequence. Most houses with wooden structures are low-rise buildings (mainly single floors), so the group sequence is basically horizontal. The basic unit of space is the courtyard, which has three forms of * * *:

First, the transverse axis is symmetrical, and the main building is placed in the center. This kind of courtyard is mostly used for ritual buildings and religious buildings with high specifications and strong commemorative, and the number is small;

Second, the longitudinal axis is the main axis, supplemented by the horizontal axis, and the main building is placed behind, forming a quadrangle or quadrangle, which is widely used from palaces to houses, with the largest number;

Third, the axis is tortuous, or there is no obvious axis, which is mostly used in garden space. There is a difference between a regular sequence and a free sequence. The most outstanding representative of the existing regular sequence is the Forbidden City in Beijing in Ming and Qing Dynasties.

In the freestyle sequence, some courtyards are integrated into the environment, and the rhythm of the sequence changes slowly, such as the buildings in the imperial cemetery and natural scenic spots; There are also courtyards that are integrated with landscape flowers and trees, and the rhythm of sequence changes is relatively tight, such as artificial gardens. But no matter which order, it is composed of overture, transition, climax and ending, and it runs through rhythmically.
