狗是怎样跳过大栅栏的？为什么？

How did the dog get over the fence and why?

我住的这个胡同是大栅栏街道(Dazhalan)的一部分，在人民大会堂附近。

The hutong where I live is part of the Dazhalan neighborhood, near the parliamentary Great Hall of the People.

大栅栏的院子里有3个单独的区域，提出花园床，平铺覆盖在侧院天井，天井前面凉棚砖。

Large fenced yard with 3 separate areas, raised garden beds, tiled covered patio on side yard, Pergola in front with brick patio.
