[3] Sung and King Hu later moved into an apartment, No.170 Boundary Street in Kowloon, and shared one big room with Li Han-Hsiang (李翰祥) and four other residents, Feng Yi (馮毅), Jiang Guang Chao (蔣光超), Ma Li (馬力), and Shen Chong (沈重).
All talented but poor, they decided to become sworn brothers and called themselves "the Idle Seven" (ci dà sián,七大閒) in 1953.
[4] Thanks to King Hu, Sung was introduced to Lo Wei and worked for his company the SWANK MOTION PICTURE LIMITED as a screenwriter.
In the following year he began to work for Shaw Brothers Pictures International Limited as a screenwriter and assistant director.
[5] His next film At Dawn (破曉時分), set in the late Qing Dynasty and based on a short story by Chu Hsi-ning, received critical acclaim and he was praised to be a "literati director".
He tried martial arts films once and directed Iron Petticoat in 1969, which led him to believe that he was not good at this popular action genre at all.
[7] A Lily in the Valley (老師．斯卡也答) is the last film Sung directed in 1982, the year when the New Taiwan Cinema movement started.
