This should be possible, standard process:

1. Click on "Merchant Free Mark" in the top right corner of Baidu map home page to complete registration and login.

If you can find the store, you can claim it directly: please enter your store in the box at the top of the map. If you can find your store, please claim it directly, and you need to upload your license qualification when you claim it. If you can't find it, please mark its location before you claim it.

3. If you can't find the store, mark it first and then claim it. Click "I want to mark" and fill in the name and exact address of the merchant, accurate to the house number. Click "Mark the location of merchants" and double-click the map to enlarge the map scale. The larger the map scale, the higher the accuracy of labeling. You need to put it at the maximum level, that is, double-click the mouse, and the map will not be enlarged until the map can clearly show the surrounding environment of your location. Refer to the landmark buildings around you, drag the red dot on the map, mark it to the position you think is the most accurate, click OK to submit, and then claim it.

4. After the application is submitted, it takes 5-7 days to review. Please be patient.

5. After the merchant information is approved, it will take 2-3 working days to be displayed on Baidu map. Please be patient.

I suggest the landlord mark the application and give it a try.

I hope I can help the landlord and hope to adopt it!
