I'm leading a group to tour Fujian and Guangdong provinces and doing either circuit (a) Xiamen, Yongding, Meizhou, Shantou, Chaozhou, Huizhou, Guangzhou or (b) Xiamen, Zhangzhou, Dongshan, Chaozhou, Shantou, Guangzhou. Could you tell me please the distance and travel times between cities to help me choose best route due to time constraints?

Thanks.
