The travel worked well with our tour guide Mr. Leo. He was a humorous guy and let our journey joyful. He explained us at Potala Palace, Jokhang Monastery and Barkhor Street about their history, legends, Buddhism knowledge and those pilgrims. We learned much thing from him! We also visited Drepung Monastery, Sera Monastery, Yamdork Lake. The monasteries were grand and people here was devout, the lake was really beautiful, like a wonderland, we took many photos here.
