Where are you from? When I was in Guangzhou, Cantonese was actually more popular abroad than Mandarin, while Cantonese and Hakka were mostly used by foreigners. If you use Mandarin, there may still be problems ~ Cantonese is already more popular than Mandarin in the world, but I don't think it will become more popular in the future. Cantonese is popular because there were many Cantonese people going abroad in the early days and Hong Kong existed. From the era of Humen tobacco to the present. But now all China people have gone abroad, not just Cantonese people. Besides, Guangdong is now vigorously promoting Putonghua. Cantonese is definitely the main force of Chinese dialects, but it will not be stronger than Mandarin ~
