What are the types of contracts? ?

Article 10 of the Contract Law stipulates that the parties may conclude a contract in written form, oral form and other forms. If laws and administrative regulations stipulate that it should be in writing, it should be in writing. If the parties agree to use written form, it shall be in written form. Article 11 further stipulates the written form: the written form refers to contracts, letters and data messages (including telegrams, telexes, faxes, electronic data interchange and e-mails) and other forms that can tangibly express the contents contained.
