Changdu is in Changdu area. You can also surf the internet. The only place where Dingqing County can access the Internet is in the business cabin of the post office, 7.5 yuan/hour. There are many Internet cafes in Changdu Town, the main ones are "New Wave Internet Cafe" and "Astronomical Computer". Both companies have ten computers, but the owners of astronomical computers forbid children and primary school students to enter and don't play computer games, so surfing the Internet here is very quiet. There are also "Net World" and "Xingyue Internet Cafe", which are located at the intersection of West Bridge and Changdu West Road in the new county. Both Internet cafes are operated by commercial houses, and they feel very comfortable after entering, but many people play computer games, which is quite noisy. In addition, the "home of net bugs" and "people coming to the net" diagonally opposite Changdu Hotel are sometimes very noisy. The above Internet cafes all use dial-up Internet access. Like most parts of Tibet, there are postal services here. It's just that his characteristics are also full of Tibetan characteristics, and the mail delivery time is absolutely long. Especially mail sent to other provinces and cities. In addition, if you want to send a parcel, you'd better do it in the capital, Changdu, because not every place can send a parcel. Most counties in Changdu have opened telephones, and IC card telephones have appeared in counties, but the number is small, and they are generally installed in the business hall of the post office. The shops in the town also have long-distance calls, and the cost is not very expensive. However, in some remote areas, Mangkang, Zuogong, Jiangda and other counties still do not use optical fiber communication, making it extremely difficult to get through long-distance calls.
