The Beijing local government has decided to allow children up to 1.3 meters tall - increased from 1.2 meters - to travel free on the subway. This is a welcome move, which will help parents of tens of thousands of children in the city to save some money, says an article of the guancha.gmw.cn. Excerpts:

From 1975 to 2005, the average height of boys aged six years in China increased from 112.3 centimeters to 118.7 cm and that of girls, from 111.5 cm to 117.7 cm. This shows that, over the past 30 years, Chinese children's average height has increased by 6 cm.

The Beijing local government's move is especially welcome because the last revision on subway fares for children was done in 2005 and the latest move reflects the development of the times.
