What are the interesting places in Langzhong? How long does it take to drive from Nanchong to Langzhong, and what is the cost? Talk about it in detail

I'm from Langzhong. How long does it take to get from Nanchong to Langzhong? It takes more than 13 kilometers to take a two-hour bus ride. The fare should be more than 4 yuan. Langzhong City and the mountains and rivers are beautiful. We visit the ancient city by taking a hill wheel car. The money driver in 1 yuan will also introduce the various characteristics of Langzhong to tourists all the way, or it's not bad to take a sightseeing bus. There are various special snacks in Langzhong, such as camellia oleifera, beef noodles, steamed buns, baoning vinegar and Zhang Fei beef.
