What are Shanghai and Shenzhen bonds?

Creditor's right is a civil right to ask others to do something (act or omission). Based on the principle of relativity of rights and obligations, it is a debt relative to creditors, that is, it must be an obligation in civil law for a certain behavior (action or omission). Therefore, the debt relationship is essentially a judicial relationship of creditor's rights and debts, and neither creditor's rights nor debts can exist alone, otherwise it will lose its meaning.
