Be careful!

If you encounter an outrageous bug, you must have made an outrageous mistake. Please carefully check your code and function implementation method.

Read documents

Reading documents is the basis of everything. You should carefully read documents and implement classic cases.

You're not the first

When you encounter a bug, you should hardly be the first person to encounter it, so you should first search and try to solve it. If not, please clearly describe your problem to your friends or community and reproduce the bug as much as possible.
