You think that ads for Tai Chi in general come from the chinese government?

Well, as far as I know Tai Chi was already cool in the west, when the communists were still fighting the practice inside china.

I highly recommend it in any case.

I have neither a positive nor negative stance towards that practice. At least the Thai government used Thai restaurants and Muay Thai as a softpower booster. It would not surprise me when China does the same. To (assumingly) spend a lot of money to get Havard of all places to advertise for something that you can also get for free on youtube is a clue in my book.

But what if it's propaganda and we improve our health and lifestyle just based on that?

Yeah, my white relatives were practicing Tai Chi before the modern chinese goverment existed lol
