Ctrip can't get a refund because of the epidemic. Can I sue?

Legal analysis: collect evidence and sue in court.

Legal basis: Article 563 of the Civil Code of People's Republic of China (PRC) may terminate the contract under any of the following circumstances:

(a) the purpose of the contract cannot be achieved due to force majeure;

(two) before the expiration of the time limit for performance, one party clearly indicated or indicated by his own behavior that he would not perform the main debt;

(three) one party delays the performance of the main debt and fails to perform it within a reasonable period after being urged;

(4) One of the parties delays the performance of debts or commits other breach of contract, which makes it impossible to achieve the purpose of the contract;

(5) Other circumstances stipulated by law.

For an indefinite contract whose content is to continue to perform debts, the parties may terminate the contract at any time, but they shall notify the other party before a reasonable time limit.
