I'm dating a Thai girl in the US right now and have been learning Thai because I want to visit Thailand and train and maybe even have a fight. She told me she wants me to learn Isan. Don't more people speak Lao than Isan? Can anyone give me more insight on Thai language dialects and what's more useful? I was thinking about training in Chiang Mai because it's cheap but she says Bangkok is better for muay thai. What do you guys think?
