Where the offeree makes an acceptance within the time limit specified for acceptance, and under normal circumstances the acceptance would have reached the offeror in a timely manner, but for other reasons the acceptance reaches the offeror after the time limit for acceptance has expired, such acceptance shall be effective,unless the offeror notifies the offeree in a timely manner that it does not accept the acceptance due to the failure of the acceptance to arrive within the time limit. 受要约人在承诺期限内发出承诺，按照通常情形能够及时到达要约人，但是因其他原因致使承诺到达要约人时超过承诺期限的，除要约人及时通知受要约人因承诺超过期限不接受该承诺外，该承诺有效。 Where the parties enter into a contract in the form of a written contract, the place of formation of the contract shall be the last place where the signature, seal, or fingerprint is affixed. 当事人采用合同书形式订立合同的，最后签名、盖章或者按指印的地点为合同成立的地点。
