Located in the southwest of the Drum Tower in beautiful surroundings, Shicha Lake has a history of about 700 years in the Yuan Dynasty (1279_1368). It assumed its present name in the Ming Dynasty (1368_1644). 
Strolling along its shoreline, the visitor can appreciate the lake’s glimmering blue water, its graceful weeping willows, its twisting railings and the flower-and-tree-covered central island. Pleasure boats are available for rowing and the banks are amply provided with shady places to rest. A swimming area in the lake is open every summer.
Shichahai Scenic Zone is the only area in the city center where vast open waters, comprised by Xihai, Houhai and Qianhai. More than 40 units for protection of historical relics are located there.
什刹海位于地安门西大街北海公园北门对面，由前海(什刹海)、后海和西海(积水潭)组成，三海（湖）相连，周围环境清幽淡雅，不同季节风景相异。夏日波平如镜，垂柳依依，荷花盛开，冬季则是天然溜冰场。两岸是保存完好的王府花园、纵横交错的市井民居，与钟楼、鼓楼遥相呼应。
什刹海地区保留了老北京的传统特色和原有的民俗文化，是北京内城重点保留地区。银锭桥横跨湖上，是前海和后海的分界线。站立桥头可饱览西山秀色，故有燕京小八景“银锭观山”之美称。
How to find the cache：
The final CO of the cache is N 39°56.AAA E 116°23.DDD , where six digits have been encoded. You should decode them with the following steps:
1, How to get the "KEY_Number"(3 digits).
In there you will see some guide and in one of them you can get the length, width and height of the Yinding bridge。 The digit of each number into a three digit by L1，W2，H3 in sequence。 It's the KEY_Number。
2, Calculate the encode number:
AAA = KEY_Number －594
DDD= KEY_Number －733
3, So, you can get the final CO and find this cache. A very nice place where you find it.
