Found its weakness!

At night.

"The Americans are too arrogant!"

"Damn, you even claimed that that was all Teacher Zhang could do?"

"That's because you people haven't witnessed how he awesome he can be when he's in form!"

"When Teacher Zhang was out there slaughtering everyone, was he not better than you?"

"You only scored a victory over Teacher Zhang in Go! What's so great about that! Do you have to get this arrogant? If you're so great, why don't we compete in other categories! Teacher Zhang was not a pro Go player to begin with anyway!"

"That's right!"

"Do you dare compete in math?"

"Do you dare compete in calligraphy?"

"Do you dare compete in piloting a plane?"

"Face-smacking Zhang would be able to demolish you people in any other aspect! Fuck!"

There was a heated discussion about this topic and all kinds of noisy chatter in the news.
