—— The anonymous Zeng Clan Association in Xinqiao Village, Shajing Town, Baoan District, Shenzhen City, Guangdong Province

The Zeng Ancestral Hall in Xinqiao Village was built in the Ming Dynasty (Yuan Dynasty) and was once the Zeng Ancestral Hall living in Xinqiao area. It is said that they are Confucius' favorite students. After Zeng Shen, he settled here in the early Southern Song Dynasty. So far, they have propagated for 32 generations and lasted for more than 800 years. Covering an area of 1.050 square meters, the ancestral hall has three rooms, consisting of eaves gallery, mountain gate, front hall, main hall and back hall. It is the largest existing ancient ancestral temple in Shenzhen. Walking through the stone archway in the courtyard, the plaque of "Zeng's Grand Ancestral Hall" above the ancestral hall gate came into view, and the pillars on both sides were engraved with this couplet. The couplet is about the sage Zeng Shen, because Zeng Shen ranks third among Confucius disciples, and later people call himself "the third family in the tree". According to legend, Zeng's descendants once lived here and advocated the inheritance of poetry and books. Only in the early Qing Dynasty, Hanlin had seven scholars, dozens of juren and scholars. The existing 10 pair of flag piers in front of the temple are relics left by the flag-raising ceremony when clan children were promoted or promoted.
