What if Ctrip doesn't open a special ticket?

Communicate and negotiate with customer service for help.

1. Communication and consultation with customer service: Passengers can communicate with Ctrip customer service to understand the reasons for refusing to issue special fares, and explain the legal and compliance requirements for passenger invoices and the importance of special fares to passengers' corporate finance.

2. Seek assistance: Passengers can contact the tax authorities for assistance, and the tax authorities can investigate this to ensure that Ctrip conducts tax treatment in accordance with laws and regulations.
