Two weeks doesn't equal seven destinations. Choose three to four areas with clear geographic clues, and use the extra days for your stay, rather than adding an airport.
Arrange a landscape chapter
After a few days in the city, places like Guilin, Yangshuo, or Yunnan will shift the course of life. Only after staying long enough can you see the morning and evening, not just a glance at the scenery.
Reserve a date for restoration
Not planning long trips and keeping only one optional plan for a day is a very practical investment. Weather, ticketing, or a chance encounter all require it.
