What I want to ask is "what is the reason for the wrong signature of the resident liaison?" This question? The reason for this is the following：

1. Input error: When inputting a signature, the signature error may be caused by spelling error, incorrect input format or other reasons.

2. Unclear handwriting: If the signature is unclear or the signature is too scribbled, it may also lead to the signature error of the resident liaison officer.

3. Authentication: In some cases, the resident liaison officer may need to provide identification or other relevant information for authentication. If this information is incorrect or missing, it may also lead to signature errors.
