Business visas typically allow holders to engage in business-related activities during the validity period of the visa. If you travel outside the invitation area while holding a business visa, it is generally possible to make purchases.
However, it should be noted that your main activity purpose should still be business-related, and your itinerary and activities cannot violate visa regulations and relevant laws and regulations.
For example, if you hold a business visa to Shanghai but make a stopover in Hangzhou during your trip and purchase some items locally, as long as you do not exceed the visa’s allowed stay and activity range, it is usually allowed.
However, if you frequently or extensively shop in uninvited places and this behavior is deemed to be inconsistent with business purposes, it may attract the attention of relevant departments and have a negative impact on your visa status.
During the period of holding a business visa, you should ensure that your activities comply with the nature and purpose of the visa.
