Travel in China (6): 你好，重庆！

Summer holiday is coming. Sally和Jolly随父母来到了“3D”魔幻之城——重庆。Chongqing is in southwestern（西南的） China. It is built on mountains， so people have to walk up and down all day. Now let’s find more fun in Chongqing with them.

来到重庆，Sally和Jolly顿时被浓雾包围。山色尽消，江岸不分，整座城市仿佛进入了“空山不见人，但闻人语响”的神秘境界。
