After getting a reply of two yuan a catty, he simply teased a few words and then began to use "Do you keep this melon cooked?" .

After angering the boss, Huaqiang went to the booth and began to appease the boss's mood, saying that if the melon was ripe, he would definitely buy it. However, after the melon was weighed, Huaqiang immediately saw through the boss's trick of hiding magnets, began to cut the boss's melon, and conveniently completed the one-on-one fight against the melon vendor. The younger brother next to him was frightened by what he saw. In the face of Huaqiang who just stabbed a man, he didn't dare to do anything except shout "Kill".
