I recommend the best route for a one-day tour in mangshi: go to Xizhen Garden in Mengbana in the morning to enjoy the plant landscape, taste Dai food at noon, visit the Shwedagon Pagoda in the afternoon to experience the history and culture, and watch the night view of Yinta Mountain and taste local food at night. This route is for reference only and can be adjusted according to personal preference and itinerary.
