We worked with Martha from China Tours.she was terrific in making all the arrangements. She was available by WeChat when we arrived in China. Hotels were top notch. The guides in each city were friendly and personable: . Ariel in Beijing , Elyshia in Xian and Warren in Shanghai. The guides assisted us at the airports or train station. Cars were comfortable. We chose China Tours because we were not interested in “ shopping tours “. We liked the guided visits to historic sights but liked having some free time to explore on our own. Would certainly use them again for future trips to China.
