A 1 hour and 25-minute layover in Taipei can be quite tight, especially if you have checked luggage. While it is technically possible to make a connecting flight within that time frame, there are several factors to consider:

1. Immigration and Security Procedures: If you are arriving from an international destination and have to go through immigration and security checks in Taipei, it can take some time, particularly during peak hours or if there are long queues.
2. Baggage Transfer: Since you have checked luggage, it will need to be transferred from your initial flight to the connecting flight. This process can take time, and delays or mishandling of baggage can occur.
3. Terminal Transfer: If your flights arrive and depart from different terminals at Taipei’s airport, you will need to factor in the time required to transfer between terminals, including any necessary security checks or transportation options.

Given these considerations, a 1 hour and 25-minute layover may not provide sufficient time for a smooth connection, especially if any unforeseen delays or issues arise. It would be advisable to contact China Airlines and inquire about the feasibility of the revised layover time. They may be able to suggest alternatives or provide additional information based on their experience and knowledge of the airport’s operations.
