      My grandpa and grandma live in America. Last winter holiday, they came to Guangzhou to visit us. First,
they flew to Guangzhou. We were all happy. They visited the Luming Lake, the zoo, the University City and
climbed Baiyun Mountain. They also took many pictures, ate good food and bought presents. They felt very
excited because they didn't come back to Guangzhou for several years. On the 10th day, they left Guangzhou
