Chaduc wire cutting accidentally pressed the tz code, and nothing could be cut.

What you want to ask is what should I do if Chaduc accidentally presses the tz code and can't cut anything? The method is as follows:

1, carefully check the code, especially the recently modified part, to see if there are any grammatical or logical errors.

2. Before making any changes, please make sure to back up the code first, even if there is an error, it can be restored to the previous state.
