趙立堅的大嘴是對的，但要注意跟川普的大嘴區別好。

趙 Big mouth must be backup with logic and common sense . Which is the case so far since his questioning and demand are reasonable given the known timeline of the related events.

Trump big mouth needs no logic and common sense.

This is due to the differences in the weights, status and roles of China and the US in the international stage. Whatever bullshits come from US people still listen while people are more critical with China.

As well, 趙 must keep bigmouthing continually otherwise it will be ineffective while Trump can stop anytime and pick it up again anytime. Yes, unfair for China, but not too bad.

Hope 趙 understands this. Otherwise, 虎頭蛇尾。
