Maybe you could demonstrate the Jyutping keyboard in your video, which is the standard Cantonese spelling system that Cantonese people use to type Chinese. Some people find Jyutping easier to learn than Chongkit.
honestly taiwanese and hongkonger can use same keyborad setting(Cangjie) because that system is invented by taiwanese, just taiwanese often to use Zhuyin Fuhao
I am from hong kong well, i don't even know how to type it in lol so just normally use hand writing board😂😂 the typing part on cantonese is even hard for a hong kongeer LOL
