We emailed Qing months before our visit and she was prompt with emails and helpful with suggestions. The day ultimately arrived and Qing was punctual and put us at ease right from the start. There was never a dull moment with her- she livened up history and facts with her own touch. Our group of 7 people had a wide range of ages and Qing paid attention to individual needs. We did Summer palace and the great wall at mutinayu with her. It was a great day!
