Many people may only know that trains and high-speed trains can buy children's tickets, but they don't know that subways and light rails also have children's tickets. Careful people must know that there is a scale at the subway ticket office, which is generally 1.5 meters high. This scale is actually used to measure the height of children who buy children tickets. Generally, children whose height is less than 1.2 meters do not need to buy tickets, while children whose height is more than 1.2 meters but less than 1.5 meters need to buy tickets.
In addition, the height of the subway station is generally calculated according to the height after wearing shoes. In order to save this little money, some parents may let their children take off their shoes and measure their height. Although this is feasible, it is not very good after all. Don't imitate it. In addition, some children may be well developed and much taller than their peers, so when they take the subway with their peers who don't need to buy tickets, they still need to buy children's tickets. Some people may protest, but this is actually in line with the regulations. After all, the standard of subway children's tickets is based on height, not age.
To sum up, children need to buy children's tickets according to the height standard when they take the subway. This is a common rule in the whole country, and it is also strictly observed by every citizen. Therefore, parents who take their children by subway still have to obey the arrangement of subway staff.
