Xiaomi's mobile phone can't pull his leg, so he needs to download the silhouette APP. The specific steps are as follows:

1. Open the wake-up app on your phone and click "+Import".

2. Open all photo interfaces and click "Photo Material".

3. Open the editing interface, slide the toolbar to the left, and then click "Car Body".

4. Open the automatic fitness interface and click "Long Legs", then hold down the white slider and drag it to the right. Pay attention. The more you drag to the right, the longer the legs in the picture.

5. Pull the leg in the picture to the appropriate length, and click Save.
