Shipi Lane is located in Xixia Street, Xitang Town. It is a narrow alley between the Wang Family "Fengtang" and "Zunwentang". According to research, under the stone road inside Shipi Lane is a sewer that makes the water all over the rain. The thin stone slab is called the skin of the sewer. Looking at the sky in the stone skin, the broad blue sky becomes a narrow and long one, so it is also known as the "first-line sky" of Xitang.
