As a language model, I do not have access to the specific data or statistics on the Shanghai Port Pass success rate for individual passengers like Yan Junling. However, I can provide some general information about how this process works.
The Shanghai Port Pass is a visa-free entry permit issued by the Chinese government to foreign citizens who meet certain criteria. The pass allows visitors to enter and exit China through designated ports without needing to obtain a visa in advance. The success rate of obtaining the pass varies depending on factors such as the time of year, the type of visa required, and the personal situation of the applicant.
In general, it is important to note that obtaining a Shanghai Port Pass requires careful planning and preparation. Applicants must submit a completed application form along with relevant documents such as a passport photo, a recent passport-sized photograph, proof of travel plans, and a medical certificate. It is also recommended to contact the relevant embassy or consulate in advance to ensure that all necessary documentation is up-to-date and accurate.
Overall, the Shanghai Port Pass is a valuable tool for travelers looking to explore China's vast and diverse regions. While there may be some uncertainty surrounding its success rate, it remains a popular choice among visitors due to its convenience and cost-effectiveness.
