This is a very serious problem that requires urgent measures to protect oneself. Here are some potentially helpful suggestions: Report to the police immediately: If you feel that your life is at risk, you should immediately call the local emergency number (such as 110) and report the matter to the police. Tell the police about Lao Wang's information and his threats, and ask them to help you take measures to protect yourself. Seek legal aid: If Lao Wang threatens to kill you, he has committed a serious crime. You can seek professional legal aid, such as a lawyer or legal aid organization, to help you protect your legitimate rights and develop appropriate response strategies. Negotiate with Lao Wang: Although Lao Wang's threat is very serious, you can also try to negotiate with him and reach a suitable solution. You can try to explain to him the reason why you are unable to repay the money, or propose a repayment plan, etc. However, if you believe there is a danger in negotiating with Lao Wang, or if his demands are unreasonable, you can choose to avoid direct contact with him. In short, if you owe a debt due to playing mahjong, you should take proactive measures to solve the problem. But if creditors resort to threats and violent behavior, you need to take immediate emergency measures to protect yourself, such as reporting to the police and seeking legal aid.
