First, determine the level of jurisdiction. In private lending, civil cases of first instance of general cases are under the jurisdiction of the grassroots people's courts; The intermediate people's court shall have the jurisdiction of the first instance if it is of great importance to foreign affairs and has great influence within the municipal jurisdiction and the Supreme Court determines that it is under the jurisdiction of the Intermediate People's Court; Cases with significant influence in the provincial area shall be under the jurisdiction of the provincial higher people's court for the first instance; Cases that have great influence in the whole country and that the Supreme Court thinks should be tried by them are under the jurisdiction of the Supreme People's Court. Then, determine the regional jurisdiction: if the IOU, loan contract and loan agreement signed by both parties stipulate the court of jurisdiction where the dispute occurs, then the creditor should bring a lawsuit to the agreed court of jurisdiction; If the two parties fail to sign an IOU, loan contract or agreement, the creditor may bring a suit in the people's court where the debtor (that is, the borrower) has his domicile or habitual residence, or in the people's court where the contract is performed. However, if there is no agreement on the place of performance of the contract, and no supplementary agreement is reached afterwards, the place of performance of the contract shall be the place of acceptance of the currency. Legal objectivity:

Article 17 of the Civil Procedure Law of the People's Republic of China has jurisdiction over civil cases of first instance, except as otherwise provided by this Law. Article 23 of the Civil Procedure Law of the People's Republic of China A lawsuit brought due to a contract dispute shall be under the jurisdiction of the people's court of the defendant's domicile or the place where the contract is performed.
