Sending a little joke

It was really damn cold this morning. My sister and I went to the ATM to withdraw some money, preparing to buy a few things for the Qingming Festival. When we got there, the cash truck happened to arrive to refill the machine. Helpless, the two of us had to stand to the side and wait miserably. At that moment, my sister said to me: Are your hands frozen? I coldly replied: Frozen! Suddenly, four guns were instantly pointed at us... Later, we were inexplicably put into a police car. On the way, we remained silent until I couldn't help but ask my sister: Why aren't you speaking? Damn, and then eight guns were instantly pointed at us... When we arrived at the police station, an officer asked my sister: What's your name? She answered: Jiang Yingyu. The officer's face turned slightly green and asked again: What's your real name? She answered: Jiang Yingyu. The officer's face turned completely green and shouted at me: What is your name? Me: (remained silent.) The officer yelled at me again: What is your name? I timidly answered: Jiang Guoyu \ Good morning, Guangzhou
