Try to write guide words of Qiandao Lake. The following is for your reference. Hangzhou Qiandao Lake A Briefing on Qiandao Lake Ladies and gentlemen, now let me give you a brief introduction of Qiandao Lake. Located in Chun’an County, Qiandao Lake is 129 km west of Hangzhou and 140 km east of Mt. Huangshan. It is the back garden of the Yangtze River Delta. The lake is so named because of the 1078 green islets in it. Qiandao Lake is actually a man-made lake, built for the Xin’an River Hydroelectric Station. So it is also called Xin’an River Reservior, the first large hydroelectric Station designed and equipped by the Chinese. The dam is 105 meters in height and 462 meters in length. At the usual water level, it covers and area of 580 km2, with a water volum e of 17.8 billion cubic meters. The water in Qiandao Lake ranks the best in China. It meets the standard of drinking water without any further treatment. In succession to West Lake, it becomes the second 5A scenic area in Hangzhou region. Two cities, both 2,000 years old, submerged under Qiandao Lake: He City and Shi City. In 1959, the Xin’an River was dammed to create a reservoir. From then on, the two counties with a long history in western Zhejiang were submerged in Qiandao Lake. He City was established in the year of 208 AD. Shi City, another ancient city, obtained its name from Five-lion Mountain. The two ancient cities were both business hubs for Huizhou merchants. After the historical events such as “eliminating the four olds” and reconstruction of and old city, it is hard to find any complete ancient city on land. Therefore, the two thousand-year old ancient cities under Qiandao Lake return to people’s memory. In order to protect the ecological environment, there is a road called Qiandao Lake Green Road. This road is named as t h e “most beautiful road” in Zhejiang. The green path is 138 km. Plum Peak Island Ladies and gentlemen, now we come to Plum Peak Island, 12 km away from Qiandao Lake Town. Plum Peak Island is located in the central area of Qiandao Lake. The name of the island is from the five hills resembling plum blossom on it. In addition to the beautiful natural scene ry , i t is reputed to be the highlight of Qiandao Lake. There are different reasons why the peak is named “Plum Peak”. One of the reasons is that before the forming of Qiandao Lake, this peak was surrounded by five small hills. Viewed from above, they looked like a blooming plum blossom. Another explanation is that many wild calyx canthus were growing on the peak in the past. Today, as a scenic spot, there are more than 5,000 planted plum trees, especially red plums, green plums, white plums and calyx canthus. It is the only place in Qiandao Lake to appreciate plum blossoms.
