1. First of all, it depends on the geographical location you mentioned. If it is a county-level city or city, it may be found on the website of the city or county, and it is very likely that it will not be found, because the office building you mentioned is good if it is the whole floor area, and if it is only half of the office; There is basically no way to check, unless it is out of that property;
2. If it is a well-known building in China, such as "Shenzhen Wang Di Tower", "Shanghai Pearl" and "Guangzhou TV Tower", you may find relevant information, but if you go to a small company or something, you may not find it; Because most offices are the same, it is not excluded that people are divided into two and two people are combined into one.
