The cast was embroiled in a water-gun fight resulting in everyone being drenched. However, the female cast was well prepared for this as they had swimsuits on the inside.
While filming for Burning Flame III was on-going, there were plenty of rumours that alleged that Wong Hei and Kevin Cheng do not get along well. At this promo event, the two male leads had no interaction with one another except towards the end when a group photo was taken. Wong Hei stood next to Kevin Cheng. Reporters quickly seized the chance to ask Wong Hei about his character, Chung Yau Sing, who offends almost everyone in the series. Wong Hei reasoned that he was not the one who wrote the script. Reporters pushed their luck and further asked Wong Hei if his real life characteristics mirrored those of Chung Yau Sing. Wong Hei claimed that he does not understand the question. He also left immediately once the event was over. The PR personnel explained that Wong Hei has other obligations and had to leave immediately.
