Why doesn't Chongqing promote this National Geographic attraction?

📆250 million years ago, due to the violent movement of the earth's crust, the Wuling Mountain Grand Canyon was born on this land. Its spectacular cliffs and crevices are breathtaking, as if they were works of art carefully carved by nature. Not only is it recommended by National Geographic magazine, it is also a natural wonder worth exploring! - 👣This scenic spot is very suitable for hiking enthusiasts, and the whole journey takes about three hours on foot. When you step on the iron rope bridge that passes through the mountain, it feels like you're walking in the clouds ☁️, and the shock is indescribable. Continue down the mountain road, and you will reach the canyon crevice, with high cliffs on both sides forming a spectacular view of the sky. The Qingfeng Gorge crevice is breathtakingly beautiful, and at certain times the sun 🌞 shines through the crevice, forming a beautiful picture. - 🚗To get here, you can drive to the Wuling Mountain Grand Canyon Service Center. - ✍🏻In Fuling, there is also a little-known secret project - the 816 Project Scenic Area. As part of the "Two Bombs, One Satellite" plan, the name of Baitao Town was not made public until 2002. Thousands of people worked hard underground here for 18 years, making a huge contribution to the country's national defense construction, and finally built this magnificent underground city. - 📸About taking photos: This place is like a real version of the underground city in "The Wandering Earth"! Not only is it shocking, but every photo you take is full of a sense of science fiction.
