How to clean up Shen Yuan Hotel?

Cleaning strategy of Shen Yuan hotels;

1. First of all, we finished the preliminary task of "Song of Dragon and Freedom", talked with the maid Adeline at the gate of Chenxi Winery to get the task, and then entered Chenxi Winery.

2. Then we need to attack with wind or water to clean the stains.

The position of the second stain is next to the carpet.

Then the third and fourth stains are on the carpet in the lobby.

Finally, after we clean all four stains, we can finish the task and get a reward by talking with Adeline.
