Legal subjectivity:

The printed signature of the IOU is valid. As long as the content of the printed IOU is true, the printed IOU with signature is also valid. In principle, the original copy of the IOU must be submitted, but if it is inconvenient to produce the original, a copy may be produced. Copies can be used as evidence in some circumstances, first of all when there are other materials cited. The second is when the other party acknowledges the contents of the copy. Legal objectivity:

Article 667 of the "People's Republic of China and Civil Code" A loan contract is a contract in which the borrower borrows money from the lender and returns the loan and pays interest when due. Article 668 of the "People's Liberation Army and Civil Code" of the People's Republic of China shall be in written form, unless otherwise agreed on the loan between natural persons. The content of a loan contract generally includes terms such as loan type, currency, purpose, amount, interest rate, term and repayment method.
