Taiwan actually rounded up tourists from the mainland and sent them back home, then locked down travel for all. They took it seriously from the start, ignored what the WHO and CCP were saying. I don't doubt there were many more reports from Taiwanese on the mainland, over just the posts by Li.
Yep...because if anyone has a huge amount of skepticism of Chinese information it's going to be Taiwan. They have recently taken a turn for the worse, but they managed through over a year with very little infections (<1,000) because they acted early and took every precaution...including travel bans. They saw a huge jump in May and took immediate action and the new infection rate is now low double digits per day.
