The first time I went to Chengde, Hebei, about 20 years ago. At that time, the waterways of the summer resort had not been fully connected. Therefore, I have the impression that the garden built in the northern mountainous area has more mountains and less water. Recently, I visited the summer resort and Waiba temple again. That day, when I passed through the Yunshan resort, went out of Xiuyun gate, left the museum area and entered the plain Lake area, the sight of mountains surrounded by water and mountains in front of me made me feel that I had come to the water town in the south of the Yangtze River. However, it is refreshing to see that the causeway, island and bridge between the lake and the lake are connected, and the scattered waterfront buildings, trees, flowers and plants are reflected on the water surface. More than 300 years ago, Emperor Kangxi of the Qing Dynasty visited the north and decided to open up a lake area and build a palace here because he liked the beautiful water and plants, close to the mountains and rivers, the strange Rehe spring echoed the chime hammer peak from afar, and the climate was pleasant and the location was moderate. There are three sources of lake water in the villa: the first is mountain stream water, the second is Rehe spring water, and the third is WuLie river water. The designer uses the river channel and natural blisters and slightly transforms them manually to form the prototype of the current Lake area. Some people call it "from nature, better than Jiangnan". Therefore, it is not surprising that there are many lakes and water in the villa. However, due to historical reasons, the waterway of the villa has dried up for more than 150 years. Until 2003, which coincided with the 300th anniversary of the construction of the villa, one of the projects for the villa people to welcome the festival was to introduce the Wulie River into the villa, and the pavilions and pavilions along the way were renovated, so that the waterways that had been dried up for more than 100 years could be restored. After buying a ticket, I went to qingquefang wharf to line up and board the ship, and began to go to the waterway villa. The green sparrow boat is not only the fifth scene of the thirty-six scenes of Qianlong in the summer resort, but also a boat used by the emperor when he visited here. It is the only moving scene in the thirty-six scenes of Qianlong. The green sparrow boat in Shanzhuang Lake area is copied according to the relevant records in the literature. It has a delicate and gorgeous appearance and is quite Royal. It is said that each green sparrow boat can carry 80 people. The green sparrow boat relies entirely on human rowing. The two ship owners each hold a long bamboo pole, one left and one right standing in the bow of the boat, holding the bamboo pole from time to time, which is more conducive to environmental protection. The cruise ship goes northward all the way, and the first stop is Jinshan. This small island built of green stones includes the 18th scene "Tianyu Xianchang" and the 12th scene "Jingshui Yunling" among the 36 scenes of Kangxi. Because the buildings on the island were built in imitation of Jinshan Jiangtian temple in Zhenjiang during the reign of Kangxi, it is called "Jinshan". Here, palaces, pavilions and corridors are scattered, row upon row and picturesque. It is one of the important scenic spots in the lake area. In the midsummer of this year, the main image of cultural and creative ice cream in the summer resort, which was once popular on the Internet, is Jinshan Pavilion. Down from Jinshan, the cruise ship sailed to Yanyu building. Under the eaves of the roof, a Yunlong gold plaque with the imperial title of Qianlong "Yanyu building" is hung. From a distance, this building is not only the same name as the Yanyu building on Yuanyang Island, Nanhu, Jiaxing, Zhejiang, but also very similar in appearance. Emperor Qianlong went to the south of the Yangtze River six times in his life. Seeing the smoke and rain in the morning and evening of the Yanyu building, he ordered the painter to describe it. When he returned to the north, he ordered a skilled craftsman to copy it. The word "misty rain" is taken from the poem "480 temples in the Southern Dynasty, misty rain on many buildings" written by Du Mu, a poet of the Tang Dynasty. It is said that when you climb the stairs on rainy days, you can see the misty rain, the water and the sky are the same, and the distant mountains and near water seem to be shrouded in light gauze mist, just like being in a fairyland. The last stop of the mountain resort by water is Rehe. We were impressed by this place because we had been here before. We decided to abandon our boat and go ashore on foot. Walking by the lake, the breeze blows, and the cool air strikes people. On the lake, green sparrow boats come and go, which makes people suddenly wonder what year it is this evening. When Emperor Qianlong visited the lake in a green sparrow boat, he looked at the emerald covered red lotus in the lake, saw the fragrant grass weaving on the shore, and saw the clear wave like a mirror. He suddenly felt that the summer had retreated and the wind came, as if he were driving a green sparrow in a fairyland. Intoxicated in the "fairyland", of course, he would not expect that one day his "imperial boat" would be widely copied, and the common people would share the experience at will... This taste made people sigh: the bleak autumn wind is again, and the world has changed! (outlook new era)
