Visitors from other provinces and cities in China who come to the South Fourth Ring Road in Beijing may need to provide negative proof of nucleic acid test and relevant health code information to ensure the normalization of epidemic prevention and control in Beijing. In addition, according to the actual situation, the Beijing municipal government may also adjust its policy of entering Beijing. If the relevant policies change, I suggest you keep abreast of the latest local regulations.
In short, if ordinary citizens go to Beijing's South Fourth Ring Road, they generally do not need to apply for a permit to enter Beijing. However, it is best to understand relevant policies and regulations before traveling and strictly abide by epidemic prevention and control measures.
