While in Foshan, his inquires regarding local Wing Chun instructors brought information about 81-year-old Master Pan Nam, the last known disciple on Painted Face Kam's branch of the family tree. Chong learned that Pan Nam had ceased teaching in 1990 and had, in fact, "closed the door" to his school. Unknown to Chong, Pan had delayed officially retiring, which involved certain formal rituals because he had a premonition that someone, his final student, was coming.
