In early March 2023, Chinese-Canadian female singer Annabelle Louie returned to Zhongshan for the first time with her family to seek roots in Dutou Village, South District. She visited the Dutou Lei's Ancestral Hall, the former site of Duxi Pier and other sites, and performed her classic song Once Upon a Time in front of her grandfather Lei Xueyi's old house. In the 1980s, Annabelle Louie rose to fame in Hong Kong with this song.
