After pandemic, anti-globalization seems to be popular around the world. That's because each country has bad relationship with some nations amid trying to impose responsibility of causing pandemic. Especially, conflict between US and China would be the harshest one. I wish they could be calmed down to solve the issue peacefully.

But, judging from the current situation about virus in Taiwan and China, Hong Kong government should turn down that ban on Chinese and Taiwanese.

Why can they move production lines?
