The Hong Kong YouTube channel Trial & Error has become all the rage in the Cantonese-speaking world with its offering of comedy skits, parodies, music videos and game shows. Founded by Hong Kong actor Neo Yau Hawk-sau, along with Hui Yin and So Chi-ho, the channel is famous for delivering shows using clever wordplay with Cantonese slang, nonsensical gags and deadpan humour. It has also found success offline, staging two sold-out live shows in Hong Kong in October 2021.
