Legal analysis: the witness is not a party to the legal relationship of private lending, and does not bear any legal responsibility for the borrower's failure to repay the loan on time. In addition, witnesses should testify truthfully and be responsible for their own testimony. If he provides perjury, he should bear legal responsibility.

Legal basis: Civil Code of People's Republic of China (PRC).
