Begin with four or five days in Beijing. The Forbidden City, Temple of Heaven, the Great Wall, and a carefully chosen hutong experience establish the scale of imperial history while also showing how the capital is lived at neighborhood level.
Continue with roughly three days in Hangzhou. West Lake, Longjing tea country, gardens, and quieter cultural encounters deliberately reduce the tempo after Beijing. Hangzhou is not filler between two larger cities; it gives the route contrast and room to absorb what came before.
Finish with three or four days in Shanghai. Historic neighborhoods, the Bund, contemporary design, food, and urban life bring the traveler into present-day China. Ending here makes the route feel cumulative: history and aesthetic tradition remain visible inside a modern city rather than being left behind.
Ten days is a focused version of the route. Twelve to fourteen days allows more unstructured time, deeper neighborhood visits, and less pressure around transfers. Travelers with fewer than ten days should normally reduce the number of cities instead of compressing all three.
