Amy has an English friend, Annie. Today, Annie and her family take a trip to China. Amy meets them at the airport(机场). First, they have some noodles at a Chinese restaurant. Annie finds Chinese food is so different from British food. And she can't use chopsticks. Some traffic rules are different from those in the UK, too. People must look right before crossing the road in the UK. But in China, people must look left first and then right. When they cross the road, Annie sees a bus. It is a double-decker! It is the same as that in London. But she can't find the door. It is on the other side. That's different and interesting!
