Which is developing faster, Daxing, Tongzhou, Shunyi and Changping?

Personally, I think it is Shunyi. Shunyi is the venue for the Olympic aquatic events. The housing price in Shunyi is nearly 1,000 yuan higher than that in Daxing, Tongzhou and Changping. Shunyi has convenient transportation. The M 15 line was completed and opened to traffic at the end of 20 10, connecting with the Beijing subway. The 7th Flower Expo is stationed in Shunyi. I think Shunyi is developing rapidly! ~
