That old Viet man has traditional methods of curing headachs lol, which works, and I think the younger generation of Asian kids are just too modern about it. They were laughing at him and such, but then his (I forgot his name) headache went away. They should learn to respect each other's culture, even being Asians together.
Anyway, it's gonna be interesting. I'm looking forward to watching it. For some reason, I think the Asian team will advance in some skills, at least because of the old man. Old people who has lived in their mother land learned ways of surviving, especially if you came from a less fortunate family and side of the country.
