Why western language learners have a command of more languages than Chinese learners？

advertisement Today , I came across one question where you can see many advertisements? walls and public transports quickly came out my lips. In China,walls are excellent places for marketing bosses to post their advertisements. Walls outside the house in the rural areas ,walls outside the shopping malls ,walls inside the subway stations ,all are packed with different kinds of advertisement from makeups to household electric appliances,from real estates to apps and the list goes on. Walls advertisement in rural areas reflect the lifestyle changes of people to some degree. When I was young ,they painted advertisement about chemical fertilizer and animal feed . Now it swifts to products related to Internet and sevice industy. Signs like Baidu brings you business opportunities , Meituan group buying makes life cheaper. The CEO of Jingdong ,a giant internet store once said ,we were fighting for the rural market by painting the walls. There are also advertisements in public transports. Bus, taxi and subway are decorated with posts about advertisement. Thanks to the large number of passengers taking the public transports in China, marketing managers are striking deals worthing millions of RMB with the transport sector.
