Take a bus at Nanchong North Bus Station. When you get to Langzhong, take bus No. 7. Get off at the east gate and walk straight ahead to the Zhuangyuanfang, the entrance to the ancient city. Taking a taxi only costs 13 yuan. In fact, walking around in the ancient city is enough. There are many interesting things in the ancient city, it depends on how you experience it. There is nothing to see in the crowded streets, but you can see many different things in some small alleys. Of course, if you just want to have fun, just walk around the ancient city, see Zhangfei Temple and Gongyuan, visit a few courtyards, take a tour boat, climb Zhongtian Tower, Huaguang Tower, and check out the Feng Shui Pavilion. Enough. I think the most worthwhile thing to appreciate in Langzhong is its humanistic beauty, but you can't appreciate it at all during the eleventh day. It can squeeze you to death. You'd better book in advance, otherwise you might end up sleeping on the street. Remember to eat a bowl of beef noodles when you go there. It is delicious and is the taste that every Langzhong person misses the most.
