The labor contract is not signed, but does giving up the job constitute a breach of contract?

Giving up work before signing a labor contract does not constitute a breach of contract. However, if a worker signs a labor contract with the company and does not go to work, it is a breach of contract. Even if the laborer doesn't want to go to work, he should inform the employer one month in advance, instead of leaving without saying anything. If the employee's resignation causes certain losses to the employer, the employer may require the employee to make compensation.

Article 90 of the Labor Contract Law of People's Republic of China (PRC) * * * If a laborer terminates the labor contract in violation of this law, or violates the confidentiality obligation or non-competition restriction stipulated in the labor contract, thus causing losses to the employer, he shall be liable for compensation.
