If you sign the contract, you will be liable for compensation. Unless there is a major misunderstanding or coercion. This is not out of the true will of the signatory, so it is necessary to bear its own obligations for the contract. If there is an obligation to compensate for breach of contract, it is necessary to pay compensation. It doesn't matter whether a shareholder signs a contract or assumes joint and several liabilities. A shareholder is liable for the company's debts with his capital contribution, and is not responsible for the company's losses if he has fulfilled his capital contribution without abusing his power.

Joint and several liability means that all responsible persons, regardless of share and order, bear the liability at the request of creditors. When the creditor makes a request, each responsible person shall not refuse it on the grounds that it exceeds its share. Agreed joint liability is the joint liability arising from mutual agreement between the parties in advance. Legal joint liability refers to the joint liability arising from legal provisions. Because there are not many cases where the debtor agrees to increase his liability, most of the joint liability comes from legal provisions. Legal joint and several liability and agreed joint and several liability not only have different reasons, but also have different subjective factors.

Joint and several liability in law means that the parties are subjectively at fault. If the agent colludes with a third party in bad faith and damages the interests of the principal, as both the agent and the third party are subjectively at fault, the relevant provisions stipulate their joint liability. It is not necessary to require the parties to be subjectively at fault to agree on joint liability, only the prior agreement shall prevail. If the guarantor in the main contract provides a guarantee for the warrantee, the guarantor is not at fault subjectively, but only assumes joint liability based on the agreement in the guarantee contract.

Article 577 of the Civil Code of People's Republic of China (PRC), if one party fails to perform the contractual obligations or the performance of the contractual obligations does not conform to the agreement, it shall bear the liabilities for breach of contract such as continuing to perform, taking remedial measures or compensating for losses.

Article 578 Where a party expressly expresses or shows by his own behavior that he will not perform his contractual obligations, the other party may require him to bear the liability for breach of contract before the time limit for performance expires.
