Taiwanese actor and host Alien Huang, popularly known as Xiao Gui, died on Sep. 16.

Preliminary investigations revealed that the 36-year-old had likely met a sudden death in his bathroom at home, where he fell and hit his head in the process.

Several overseas media outlets also reported that Huang had also suffered a heart attack.

He was later discovered by his father, but had already passed on by then.

Since news of his abrupt death spread, celebrities from both Taiwan and Singapore have paid tribute to Huang.
