What is su chinese character?

Su (宿) is a Chinese character that means "night lodging" or "constellation". It is comprised of two radicals, with 宀 on top representing a roof or home, and 谷 on the bottom representing a valley or enclosure.

In Chinese culture, Su is often associated with the Twelve Earthly Branches and the Twenty-Eight Lunar Mansions. The Twelve Earthly Branches refer to the twelve animals in the Chinese zodiac, each of which is associated with a different hour of the day. The Twenty-Eight Lunar Mansions, on the other hand, are a traditional division of the night sky into twenty-eight sections, each of which is associated with a particular star or constellation.

In ancient times, Su was also used to refer to inns or lodges where travelers could stay overnight. This is a reflection of the character's original meaning as a shelter or dwelling place. Today, Su is still used in modern Chinese writing and is a common component of compound Chinese characters related to lodgings, hotels, or overnight stays.
