Precautions before use:

1. A single run typically consumes around 50 coins, but the actual consumption depends on the runtime, and it may exceed 50 coins significantly.

2. The generation effect of Wanxiang is not stable. Good results still require multiple attempts. The sample video was achieved after several tries. If the effect is unsatisfactory, you can try changing the random seed and testing again.

3. Better results are easier to achieve when the proportions of two people's images and backgrounds are similar.

4. Prompt words can be further supplemented and optimized by yourself.
