Was Ka Kui Wong assassinated by the Japanese?

It is said that Ka-kui may be killed, because Ka-kui offended the entertainment circle in Hong Kong by talking too much in Honesty and Frank, and then went to Japan to develop. When doing this entertainment program, both hosts wore helmets. Except BEYOND4, they played a game of balloons with a lot of water, and the layout was very slippery. The pony fell. He died six days later. The result of treatment in Japanese hospitals is the practice of the mage. He took the elixir of life and other drugs, but Ka Kui didn't get the best treatment! Ka kui just left. . .
