My Date with a Vampire Season 2

Fong Kwok Wah and Yamamoto Ichifu clash again in 1938, and their fight arouses the attention of Cheung San (the progenitor of all vampires), who interrupts the fight. Just as Cheung San is about to bite the two men and turn them into vampires, Ma Dan Na appears and attacks Cheung San, driving him away, thus sparing Fong and Yamamoto from their fates. Not long later, Fong agrees to help Ma hunt down and destroy Cheung San. They succeed in trapping Cheung San, but he breaks free and bites Fong and the boy Fuk Sang (who is nearby), transforming them into vampires.
Fong Kwok Wah and Fuk Sang survived until the present day (the 1990s), and their physical appearances have not changed since 60 years ago. However, before Fong became a vampire, he already had a son with his wife, Sau, so he now has a grandson named Fong Tin Yau. Fong Tin Yau is killed in an incident in England, so Fong Kwok Wah impersonates his grandson. He meets Ma Siu Ling (a descendant of Ma Dan Na), the heiress of a clan of ghostbusters who have dedicated themselves to ridding the world of evil supernatural beings. Fong starts a romance with Ma.
