The shuttle bus is really convenient. There are many boarding points, all in areas where tourists congregate. It's a direct route with no transfers, and the return trip is quick and easy, saving time and money. Our guide, Mr. Xie, is diligent, responsible, polite, and speaks with great manners. His museum tour was excellent value for money, though not mandatory. The two-hour tour was very professional, and I was very satisfied. It would be even better if the shuttle bus had stronger cooling.
