We had a wonderful time in Tibet. We have learned a lot about this unique destination because of the wonderful guide Degyi who is so knowledge and always available towards our tours. We stayed at the Shangri-La Hotel Lhasa, and we would never imagine a Tibet travel could be so nice and amazing without the help of Degyi.

Also, thanks a lot to our Tibetan driver Mr.Wongdun for his safe driving and a good sense of service along the way.

We shall return Tibet in the near future!

Dujiangyan Irrigation ProjectThe Dujiangyan Irrigation Project in Southwest China's Sichuan Province represents ancient China's superb science and technology and is a milestone in the world's water harnessing and irrigation history. Dujiangyan, the world's oldest diversion project without a dam, still feeds a grid of irrigation canals watering 670,000 hectares (1,675,000 acres of farmland in Sichuan, turning the province into the country's famous land of abundance since ancient times.

Dujiangyan is the oldest and only surviving no-dam irrigation system in the world; and a wonder in the development of Chinese science. The project consists of three important parts, namely Yuzui, Feishayan and Baopingkou scientifically designed to automatically control the water flow of the rivers from the mountains to the plains throughout the year.

Dujiangyan Irrigation ProjectYuzui, like a big fish lying in the Minjiang River, is a watershed dividing the river into two parts Inner River and Outside River. FeishaYan is a spillway that diverts the sand and stones of the inner river into the outer river. Baoping Kou, like a neck of a bottle, is used to bring water into the inner river from Minjiang. At the same time, Baoping Kou controls the amount of the intake water due to its reasonable location. These three parts interact with each other perfectly to form an effective water conservancy project. During the low-water season, 60% of the Minjiang water is brought into the inner river for irrigation while 40% of the water is drawn into the outside river. The situation is reversed in the flood season ensuring the water supply for irrigation and protection from flooding on the Chengdu Plain.

There is a magnificent bridge called the Anlan Cable Bridge crossing the Minjiang RiverDujiangyan Irrigation Project above Yuzui, which is the most scenic place in Dujiangyan. The construction of the bridge originally commenced before the Song Dynasty (960-1279). At that time, the body of the bridge was constructed with wooden blocks and the handrails were made of bamboo. Recently the wood and bamboo were replaced with steel and reinforced concrete to ensure the security of the visitors. Seen from afar, the bridge looks like a rainbow hanging over the river. From the bridge, you can clearly see the entire layout of the Dujiangyan system.
