If the non-competition period is not exceeded, you must abide by the confidentiality agreement.

1. Violating the confidentiality agreement must first bear civil liability. Civil liability can be divided into breach of contract liability and tort liability. The employer may require the employee to bear the responsibility for violating the confidentiality agreement, or it may choose to require the employee to bear the tort liability for compensation for losses.

2. Article 219th of the Criminal Law commits one of the following acts of infringing business secrets, and if the circumstances are serious, it shall be sentenced to fixed-term imprisonment of not more than three years and fined. If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years, and shall also be fined (1) obtaining the business secrets of the obligee by theft, bribery, fraud, coercion, electronic intrusion or other improper means; (2) disclosing, using or allowing others to use the business secrets of the obligee obtained in the above way.
