Zhang Tiezhu came home drunk at night. I met a yellow-skinned creature without a tail and asked for a seal. Huang Pizi said, "Do you think I look like a human or a god?" "Haha, you have legs like your grandma!" Huang Pizi said, "Brother Zhang, stop making trouble and talk to me!" Zhang Tiezhu said, "Pizi, I tell you, you must believe in science these days." Huang Pizi said, "I am a Huangxian, but I believe in science!" Zhang Tiezhu said earnestly, "I am doing this for your own good!" From then on, he went on a road of no return.
