Loong and crew, so used to Yam looking over their shoulders, were not natural in speaking up on film set in 1976. Eventually, Loong picked up the necessary mentality as the chief and then Lang Chi Bak slowed Loong down when classmates were behind at manuscript reading as a group. Back in 2004, Loong requested musicians to pick up their pace but in vain. Returning after 12 years, Loong was caught off guard by the prevailing melodramatic style. All that happened in front of the Press in 2004. What made the performance "stale jau4 zaa3 gwai 2" (就像隔夜油條) was caught on tape in 2005. Finally Loong could put back on stage the Yam signature style in 2015/6, without undue influence any more and working with compatible co-stars and musicians. At the same time, Loong stopped hiring performer who refused to play the designated roles. Her hands were tied by coat tails back in 1980s. A performer got away with big fat paychecks without, playing all roles designated, filling the shoes left behind by the one before him.
