Stone vegetable field is the abbreviation of Liao. "Tianxia Caitang" comes from the name of Liaogang Imperial Seal Hall in Song Dynasty. The "Chua's Hall" was originally surnamed tang of Liao surname in Liaogang, but because it was sealed by a decree, and "Chua's" means "France and China are handed down from generation to generation", it is auspicious and elegant, and many Liao surname families who are not in Liaogang also take "Chua's" as surnamed tang. Surnamed tang used by people surnamed Liao in Changning is also "Chua's". In the past, there were many villages with Liao surname. Above the gate of the public hall, the four characters "Chua's Hall" were written. There are also many private houses with the words "Shi Caitang" written on the back wall of the main hall, which shows the weight of the name "Shi Caitang" in the hearts of people surnamed Liao.
