Please tell me what kind of sapling this is (durian sapling was bought at that time).

Using map recognition software to identify the plants in the map, the recognition result is papaya tree.

Durian saplings are definitely not. The back of durian leaves is smooth, while the back of the leaves in the main picture has long hair. Below are pictures of papaya saplings and durian saplings, and the subject can compare them.
