Do I need a Taiwan visa when I transit from Seattle to Taipei and return to Shanghai? Do I need a Taiwan visa to leave the country the next day after customs clearance?

Can't do it, entry quarantine...<br/><br/>From midnight on March 19th, non-Taiwanese nationals are restricted from entering. All arrivals are required to self-quarantine at home for 14 days. <br/><br/>Help you, please click green to accept!

Taiwan has long since refused to allow entry. I heard that the border crossing has not been given recently. So don't buy this ticket.
