The bar chart illustrates the number of domestic deliveries from 2018 to 2020. As it shows, both urban and rural express deliveries rose slightly. However,the quantity of city deliveries was much higher than the countryside's, being almost three times more than the latter. There are two reasons for this phenomenon. The main one is the economy. People's living standards have improved and so they have spare money to shop online. Chinese infrastructure has been built, for example, high speed roads and other transportation methods which help to speed up deliveries. The second reason is convenience. Being busy with working and living, more and more people prefer to use online services instead of going to malls in person. This can help them save time and compare prices directly.
