How to mark multiple locations on Baidu mobile phone?

Baidu map APP marks multiple geographical locations;

For example, I want to mark the geographical location of Home Inn.

1. Click the second icon in the upper right corner (as shown in the figure) to confirm that "Favorites" has been opened.

2. At the bottom of the map, click "Details" next to "Home Inn".

3. Then click the "Favorite" button in the upper right corner.

4. If you want to check the geographical location of Home Inn in the future, open Baidu map and click "My"-"My Collection"-"Home Inn" at the bottom, you can go directly to the map and see the yellow pentagonal symbol made on the map.

Note: Other geographical locations are shown above.
