Do you need to provide English reservation certificate and air ticket for tourist visa? How should this be obtained? Thank you very much.

You don't need to provide reservation certificate and air ticket when you apply for a tourist visa, but you will be required to provide air ticket or even reservation certificate when you leave the country and enter a foreign country with a tourist visa.

Tourist visa is the permission of the destination country to enter the country for the purpose of tourism. When applying for a visa, the permit has not yet been issued, so naturally there will be no reservation before the visa. However, it is normal for passengers to show their tickets and reservation certificates when they have obtained tourist visas and arrive at entry and exit ports, such as China's international airport or foreign airports. Border checkpoints in many countries also require checking whether inbound tourists have enough cash to maintain a normal travel life without economic difficulties and affecting travel.
