In business cooperation, the concepts of fairness, integrity and transparency are the basis for long-term cooperation and mutual benefit and win-win situation. Our country's law clearly stipulates that the conclusion of contracts should follow the principles of equality, voluntariness, fairness, honesty and credit. Any attempt to design unfair contract terms through improper means not only violates business ethics, but may also lead to the contract terms being deemed invalid or revoked by law, and even face legal liability. We recommend that you fully respect the rights and interests of both parties in the contract, clarify your respective responsibilities and obligations, and consult a professional legal person if necessary to ensure that the contract is legal and effective. Honest management and fair cooperation can not only establish a good business reputation, but also the fundamental way for the sustainable development of enterprises.
