Analysis on the Route of Xu Clan&;s Moving into Guangdong 1. During the reign of Emperor You of Song Renzong, Xu Xinguang (Zejiang) was a scholar, and he was admonished by the official in the book. He married Dong Shi and gave birth to three sons: Chang Zongshan, the second Zongli, and the third Zongyuan. He came to Guangdong Nanxiong Zhuji Lane with his three sons from Jiangnan.
