How should I plan a 5-day itinerary in Yunnan?

Start with Kunming (Stone Forest, Dianchi Lake), then travel to Dali (Erhai Lake, Ancient Town) by high-speed rail. On Day 3, visit Lijiang (Old Town, Jade Dragon Snow Mountain). Day 4: Shangri-La (Potatso National Park). Day 5: Return to Lijiang or Kunming. This route balances nature and culture for first-time visitors.
