Do I need to wear a down jacket when I go to Jiuzhaigou in March? It is said on the Internet that people from Zhejiang are free of admission. Is this true?

There is no need to wear down jackets in March. The ticket discount policy is until March 31. There is no announcement of free tickets. The hotel recommends you to stay (Heyeying Hotel), and there is no hotel closest to the mouth of Jiuzhaigou. hope this helps.
