What does the ridge in the Golden History refer to?

The ridge mentioned here is not a real ridge, but refers to Dawang Mountain in the east of Guangdong Province from north to south. Although it is called a mountain, the altitude is relatively low, so it is more correct to call it a mountain. The most important city to the east of Dawangshan is Shantou. Therefore, people often call Shantou the gateway to Lingdong.
