More methods were also added, forming a complete mode to control the sand and protect the railway.

Over the years, as people advanced, the sand retreated, turning Shapotou into a model of sand control.

Now, the desert in Shapotou has become an attractive scenic spot for travelers.

"When I stood in the desert, I was so excited that I sent a message in my Wechat Moments to declare my arrival," said Wu Qiuhuang, a visitor to the zone.

When sand is no longer a serious threat, the scenic zone can continue its development to attract more visitors.
