My name is Lily. I’m a junior high school student from Guangzhou. Last winter holiday, I visited Hong Kong for the first time with my mother and her workmates. Before we went through the entrance of the Customs and Excise Department (香港海关，缩写为CED), we had to wait for more than four hours there. All the passengers must show their permits (许可证) to the workers at the CED one by one. So there were a large number of people waiting in lines at the entrance hall. It took us a long time to walk along the metal pipes which divided the big hall into many different parts. So the entrance hall looked like a huge puzzle. Everyone should finish walking through the puzzle if they wanted to pass the entrance. I waited patiently and walked slowly after others. I just could see the back of their heads. It was difficult for me to breathe because too many people were there. At last I passed it but I was too tired to say a word.
Last month I visited Hong Kong again. But this time I didn’t spend much time waiting at the entrance of the CED because I got an Electronic Exit Permit with an “Electronic Brain” in it. When I passed the port of Hong Kong, I just needed to use it to touch the button at the entrance. It can save much time for people. I plan to visit Hong Kong again sometime in the future.
