Do I need to drop the lawsuit after receiving the letter from Bai Hua's lawyer?

You can ignore Bai Hua's lawyer's letter, but the other party may bring a lawsuit to the court. The general lawyer's letter belongs to the pre-litigation mediation notice. If the borrower still fails to repay the debt as soon as possible, the creditor will bring a lawsuit to the court and ask the borrower to repay the debt.

Legal objectivity:

Article 676 of the Civil Code of People's Republic of China (PRC) If the borrower fails to repay the loan within the agreed time limit, it shall pay the overdue interest in accordance with the agreement or the relevant provisions of the state. Article 678 of the Civil Code of People's Republic of China (PRC) * * * The borrower may apply to the lender for extension before the repayment period expires; If the lender agrees, it can be extended. Article 667 of the Civil Law of People's Republic of China (PRC) is a loan contract in which the borrower borrows money from the lender, repays the loan at maturity and pays interest.
