He was part of Chang Cheh's ensemble of fourth generation actors along with Chiang Sheng, Philip Kwok, Lo Mang, and Sun Chien.
[2][3] Lu, along with Chiang, Philip Kwok, Robert Tai, and Ricky Cheng Tien-Chi would practice acrobatics near Taipei Bridge and earned pocket money playing extras in movies that were shot nearby.
In addition to acting, Lu briefly worked as a stuntman in some productions including Ng See-yuen's Secret Rivals 2 (1977), where much of his previous acrobatic training was applied to the action choreography.
[5] Following Long Bow's closure in late 1976, Lu, along with Chiang Sheng, Philip Kwok, and several other actors left with Chang who relocated back to the Shaw Brothers Studio in Hong Kong.
Lu's fellow Venom actor Philip Kwok attributed the split to them simply leaving Shaw's with Chang following suit,[3] while another costar, Lo Mang, believed it was due to audiences no longer wishing to see gory heroics, preferring instead the lighter, more comedic tones of Jackie Chan films.
[2] Lu, similarly, was of the opinion that the split was caused by the decline of martial art films in Taiwan and Hong Kong, and because Chang had shifted his focus to the mainland market.
[2] In 1981, Lu returned to Taiwan where he, along with Venom costars and close friends Philip Kwok and Chiang Sheng made their directional debut in Ninja in the Deadly Trap (1982).
[11] Lu's film appearances decreased after completing Shanghai 13 (1984) as he shifted primarily to television at the suggestion of his childhood friend and fellow Shaw's actor, Ricky Cheng Tien-Chi.
