Why do you need tickets for Nanjing Road Pedestrian Street?

Does the subject want to ask "Does Nanjing Road Pedestrian Street need tickets"? Don't. Official website of Nanjing Culture and Tourism Bureau introduced that Nanjing Road Pedestrian Street is the first commercial street in Shanghai, which also witnessed the historical development of Shanghai. The earliest place was the seat of the concession, and foreign colonists entered Chinese mainland very early. At that time, they chose a place near the Huangpu River to build the first racetrack. Later, when the land price soared, foreigners sold the racetrack. Another kilometer was moved in, and a second racecourse was built, and a road extended from the original first racecourse to the second racecourse. Later, many people opened various shops here, and this road is Nanjing Road. There are many large shopping malls now, so there is no need for tickets.
