Moreover I was wondering if you had any video’s relating to saying no and yes in Chinese, very basic I know but a common question. I was told from a website, saying no is done by just adding the ‘bu’ negative to shi ‘it is’ or dui ‘true’, bu shi and bu dui but I am not yet fully sure when its appropriate to use them in the language.

Thank you and you are indeed the best Mandarin teacher I have come across!
