Tang was born in Heilongjiang province, northeastern China. Upon graduating from the Guangdong Sun Yat-sen Memorial Middle School, Tang reportedly attended the Shanghai Fine Arts School and also the Shanghai Baptist College. With the outbreak of the Second Sino-Japanese War, Tang fled south to Hong Kong in 1937 where he joined the Kok Sin Sing Opera Troupe (覺先聲粵劇團) led by his double (cousin) in-law and one of the "Four Super Stars" Sit Gok Sin (薛覺先). His first wife was the tenth sister (Sit Gok Ching, 薛覺清) of Sit while Sit was married to his paternal first cousin (唐雪卿). Tang worked as a copyist and assistant to Fung Chi-fen (馮志芬) and Nam Hoi Sup-sam Long (南海十三郎), two famous writers for the troupe.
