Today is the first day back to school after the May Day holiday. In 2016, May Day fell on a Sunday and was rescheduled. Monday, May 2nd, was also originally a holiday. It was a public holiday, but for senior high school students, all holidays are clouds in the sky. While others were still enjoying their last day of vacation, senior high school students trudged their way back to school.,Yue Yun walked leisurely, hearing a familiar voice. She immediately turned her head and saw an old man setting up his stall in front of a shop. She sheepishly stuck out her tongue and hurried over, "Grandpa Li, you're here again today",Le Yun praised each new item, admiring the other trinkets again. Grandpa Li was sometimes unreliable, bringing back only cheap knick-knacks, but sometimes he got incredibly lucky and found real treasures. Once, he found a Republic of China Yuan Datou coin and sold it for ten thousand yuan.。
