I haven't used a cost-effective tour group purchase. Some groups buy 78 yuan and charge Old Town of Lijiang maintenance fees.
You have to show the maintenance fee of the ancient city when you go to Yulong Snow Mountain, Black Dragon Pool and Shogunate, and you have to show it when you visit Old Town of Lijiang. If you don't go to these three scenic spots, you don't have to buy them. If you want to go, you can buy it when you arrive. A ticket for 80 yuan, valid for one week, must be used in these days, otherwise it will be invalid. Lijiang Jinsha Tourism Outdoor Xiao Mu answers your questions, hoping to help you.
