More than 200 sightseeing spots near Shanghai on China’s east coast will try a new policy – free admission for children based on their age and not simply their body height.

At present, various attractions have different rules on whether they admit children for free. For most facilities, the easiest and most popular way to manage this decision is checking how tall a boy or girl is.

For instance, the standard fare for adults at the Shanghai Tower Observation Deck in Shanghai’s Pudong New Area is 180 yuan per person, while children under one meter tall are allowed to get in free. But those who are 1.0-1.4 meters tall, only have to pay half price.

Shao Zhuqing, deputy secretary of the Shanghai Center Building Construction Development party committee, told The Paper the Shanghai Center had wanted to allow all children aged three or below free entry. So, they said parents would not have to pay for all children under one meter tall.

However, an increasing number of Chinese parents weren’t happy because their children, especially those aged around six, who were also supposed to be allowed in for free, were not given free admission because they were taller than one meter.

That led to the Yangtze River Delta Consumer Protection Committee Alliance advocating a new method so children could gain free entry – it said children’s age and not just their height must be taken into consideration.

And now, more than 200 sights have agreed to adopt this initiative.

Starting from July 1, children who are taller than average will also be given free admission if their parents can provide valid documents to verify their age and identity at ticket offices.

The Shanghai Disney Resort is one that has agreed to the new rule for free or preferential tickets for children, based on their height and age.

However, they want more time to set up the new terms and definitions before it is implemented.

Many top destinations including the Oriental Pearl, the Great World, the Wild Wild Insects Museum, and the Bund Sightseeing Tunnel have yet to follow this trend, largely because they already face congestion at ticket offices. And, if the policy of checking of identification documents is permitted, these sights will surely face even longer queues.
