The mainland is still 1.4 billion people and almost a quarter of the worlds economy.It’s only spoken in the mainland though. HongKong, Taiwan and Macau DONT even speak Mandarin themselves
mandarin is also spoken in Taiwan and half of Hong kongers are fluent in it too I’m not sure about macau tho. It’s also spoken in Singapore and seems like it’s gonna be a second language of sort in countries such as Malaysia, Indonesia,Thailand, Cambodia, Korea etc and maybe even Japan...thats half the world’s population. That and I like how it sounds so Inah allah I wanna learn it oneday maybe when I go to a uni in china
