Where to travel can't help others?

There may be several reasons why tourism can't help:

1. Bad network signal: change the local area network and see if it can be loaded successfully.

2. Problems of the system itself: Too many users or other reasons may lead to the failure of power-assisted loading.

3. Improper operation: If you don't follow the relevant operation when giving assistance to others, it may lead to the failure of assistance loading.

These are the possible reasons why traveling there can't help. If necessary, you can consult the official customer service for details.
