If canceled more than 7 days before departure, neither party bears liability for breach of contract provided no actual expenses have been incurred. If cancellation is proposed after this period, the party proposing the cancellation bears the liability. [the organizing team Travel Breach]: If the group fails to form and notice is given within 7 days before departure: Full refund plus a penalty (10% for 7-4 days; 15% for 3-1 days; 20% on the day). [Participant Breach]: Cancellation 7-4 days before departure: Pay 50% of the total tour fee; Cancellation 3-1 days before departure: Pay 60%; Cancellation on the day of departure: Pay 80%. If this is insufficient to cover actual losses, compensation is based on actual losses, not exceeding the total amount.
