在申请签证时，申请人应在签证申请表上注明拟入境的次数、在华停留的最长时间。签证被批准后不得进行更改。申请人如改变计划行程以至于签证次数或停留期不能满足实际需要的话，可以重新进行签证申请，但需再次递交申请材料并交费。
When applying for a visa, applicants should indicate the intended number of entries and the maximum duration of stay in China on the visa application form. Once the visa is approved, no changes can be made. If the applicant changes the planned itinerary to the extent that the number of entries or duration of stay on the visa cannot meet the actual needs, a new visa application can be submitted, but the application materials need to be resubmitted and a fee needs to be paid again.
