The Civil Code was adopted by the Third Session of the Thirteenth National People’s Congress on May 28, 2020, and will go into effect on January 1, 2021, when the era of the Civil Code in China will begin. The Contract Part accounts for more than half of the Civil Code in length and involves more substantial amendments. This article is mainly focused on the substantial amendments to the general principles under the Contract Part, which apply to all contracts, and also covers several nominate contracts, which are subject to relatively larger scale of amendments, to briefly introduce major precautions for the reference of the readers.
