What is Xi 'an's earth gate? Is it Tumen village or?

A dirt door is to open a distant door. In the Tang Dynasty, Chang 'an City (outside Guocheng City) opened twelve gates, Mingde Gate was in the middle of the south, Qixia Gate and Anhua Gate were in the east and west respectively. Chunming Gate is in the east, while Yanxing Gate and Tonghua Gate are in the north and south respectively. In the west is the Golden Gate, and in the north and south are Yanping Gate and Kaiyuan Gate respectively. Today's Kaiyuan Gate (Tumen) site is located in the western suburbs of Xi City. The Xi subway 1 line under construction is set up here. The name of the station is kaiyuanmen station. Jia Pingwa's novel Tumen is for this purpose.

Now Tumen refers to an area in the western suburbs.
