By using China's 144 hours visa-free transit, I visited Shanghai, Hangzhou and Suzhou during a voyage round the world. Cathy was our local tour guide, and she was absolutely wonderful. She is a Wikipedia with plenty of knowledge on the colonial history of Shanghai and landscape architecture of Suzhou gardens. Service was outstanding, and I was taken care of all the way from disembarkation to boarding. Sincere thanks go to my guide Cathy and the tour company Elysian Tour.
