The rapid success of China’s bike hire companies took everyone by surprise. As you can see, there are spaces in Beijing which are now totally crammed with bikes. The beauty of these is you scan them with your phone and then leave them wherever you like for the next person. Some of those complaining about the bikes want to park cars on the footpath.
在中國，自行車租賃公司的迅速成功讓所有人大吃一驚。你可以看到，北京的一些街道上完全停滿瞭自行車。這些供租賃的自行車的妙處在於，隻要用手機掃一掃，人們就可以騎走自行車，使用完後則可把車放在任何一個地方，以供下個人使用。一些抱怨自行車占據瞭城市的空間人其實是想把機動車也停在人行道上。
