We had already discussed the first video here:
Vietnamese variety, but the second one is new, posted just this February (and apparently also filmed that month). It's a great clip: the top battle is first rate!
The caption and about half of the comments are in Hmong, the rest of the comments are in Vietnamese. I'm guessing the players are Hmong.
I'm amazed at the aim: there are only 2 or 3 misses in the whole video!
I looked carefully to see if the attacking top was actually spun or just thrown as a rock with a string. Most of the time the strike is too violent to tell, but there are a few instances in which the attacking top remains spinning (e.g. @1:18), so yes, it's a true top battle. There seems to be some delayed shouting in a couple of cases when a target top is expected to be dead but actually remains spinning (after bouncing on the back dirt wall.) What I wonder is if the attacking top needs to spin after the hit to count: it doesn't seem so, but it's not clear
Thanks for posting this, Cecil.
