Do I need to land on the plane when the health code in China is valid?

No need. According to the regulations, the flight departure time should be within the validity period of China Health Code. In case of flight delay or cancellation, passengers can continue to take the flight if the new flight time is within the validity period of the health code. There is no requirement that China's health code is valid until the plane lands, as long as it is valid at the time of takeoff. In order to ensure the health and safety of people who travel from the Philippines to China, according to the latest domestic prevention and control requirements, people who travel from the Philippines to China should apply for health codes, which are called "health codes for going to China".
