48 hours in train - WHY everybody clean the windows without hesitate?

Tibet The city of Sunshine. This is a place that has more than 300 days of sunshine a year. It is also a place that Buddhist gor for their "holy trip" other than Bhutan and Nepal. I was catching the Best Scenic Train depart from Shanghai to Tibet, which takes about 48 hours for a single journey. When changing the train at Xi-Ning, all passengers were sled-driven to clean the windows from in and out: this is because this is the most scenic way of China railway. This train pass through the rivers, the fields, and seeing the glaciers from the train window. You could also see the snow fox by chance! Yarks are all along the journey with you just outside the window! I could see the cloud is so near to the mountains, the historical Potala Palace which the Buddha in the Palace was brought by the Princess Wen-Cheng to Tibet when she married the prince of Tibet. It is also the graphic 50 Yuan when looking it from Mountain Yao-Wang. In the past, the temples in Tibet, it's not only a place to learn Buddhism, it's a school to learnt arts, science, music, astronomy, geography etc. The monks are debating to each other to share their knowledge, to discussing the knowledge they gain from books and daily life. #travel Here in Tibet, you need to slow down at leat one tone, because at the land of 4000 a.s.l, every fast pace will make you hard breathing, as the scenery are so nice, why are you rush live the daily routine? #china #discoverchina
