ROC passenger traveling 6 days with no compatriot pass or visa

There are no visa-free transit options available for Taiwanese passport holders. You must apply for a Taiwan Compatriot Permit on arrival to to continue traveling. Don't forget your ROC ID card. The fee is 50 CNY plus whatever they charge for a photo.

The permit is valid for 3 months but you can apply for a 5-year permit at one of the Exit and Entry Administration offices with a registration confirmation issued either by the hotel or the local police station. Like all other foreigners (despite not being considered as such) you need to register yourself at a police station within 24 hours of arrival if not staying at a hotel.
