International passengers piled into China on Sunday despite a surge in Covid-19 cases in the country.
China has lifted quarantine requirements for inbound travellers, ending almost three years of self-imposed isolation.

Chinese people rushed to plan trips abroad after officials last month announced that quarantine would be dropped, sending inquiries on popular travel websites soaring.
