Below is the lower reaches of Leshan, mainly shipping.

There is a great difference in topography between the left and right banks in the basin. The right bank is the main water conservation and recharge area of rivers in the basin, with high mountains and steep slopes, deep gullies, vast land and sparse population, abundant rainfall, dense forests, good vegetation coverage and dense tributaries. The left bank is relatively flat, densely populated and has less rainfall. Excessive reclamation leads to extremely low forest coverage and serious soil erosion, which is the source area of river floods.

Floating on the river

Taohuayuan is located in the southwest of Changde City, Hunan Province. Tao Yuanming, a poet in the Eastern Jin Dynasty, made the Peach Blossom Garden famous all over the world. For thousands of years, Peach Blossom Garden has attracted countless tourists with its unique and beautiful style, which has fascinated many tourists! She is famous for mangroves, green hills and ancient sunset boulevard. The mountains are full of deep valleys, gurgling and meandering, gathering phoenix, purifying spirit and overflowing rhyme.

The water is green, the clouds are green and the streams are muddy. When everyone is immersed in the occasional Huang Mao poem and sometimes Bai Yunsheng, they will have a deep and quiet feeling.

Legend has it that Taohua Forest is the place where Wuling fishermen meet, which is this forest. Whenever the peach blossoms are in full bloom, the red clouds float and soar, which are magnificent and colorful, and contrast with the pine and bamboo wind by the stream. It can be said that peach blossoms are in a hurry, and there is no heaven and earth outside the world.

The bridge we are boarding now is called the poor forest bridge, and it is called Taohuayuan. Want to be poor. Under the bridge, the water is gurgling and the peach blossoms are brilliant. It is said that Wuling Yu Lang walked along the stream and came to a peach blossom forest, which surprised him. Although Taohuaxi is not as wide as before, the peach blossoms in the spring breeze are still smiling.

The beautiful building in front is the Chrysanthemum Garden, which was built in the Wanli period of the Ming Dynasty. It turned out to be Yuanming Temple. Because Tao Yuanming loves chrysanthemums, he changed his name to Chrysanthemum Garden. There are couplets at the door: but it is strange that Wuling fishing has been collected from the mouth of the cave, keeping ancient tourists busy; If you want to find Peng, ask if the garden is safe and the peach blossoms are still in bloom. It is said that Wuling fishermen went out of Xanadu, revealing a fairyland on earth, which attracted tourists from all ages to ask Tao Yuanming where the beautiful scenery of fertile land is. Only peach blossoms and running water will never change.

Go into the gate of Chrysanthemum Garden and have a closer look at its architecture. There is a fence around the chrysanthemum garden, and several windows are open. The entrance is a fish pond surrounded by cloisters. With the topography on both sides, carved columns are trimmed with bamboo, and Gui Lan is fragrant. The upper stone bridge crosses vertically, and the lion is like a monkey, crouching around; Behind the pool is the garden, Kim. In the middle is the stone carving of picking chrysanthemums in the East Column of Yuanmingyuan, followed by the poem "Peach Blossom Garden". Picking chrysanthemums under the east fence, you can see Nanshan leisurely. This quaint, elegant, beautifully carved and flowery building is Yuanming Temple.

On the pillars of the main porch, there is a couplet summarizing Tao Gong's character:

I love Ju, pride and honor, and it is hard for me to bend over and resign from pengze county. I am addicted to alcohol, not rich, and I hope to grow beans in the south, and I belong to Teacher May 6th. He wrote that Tao Yuanming loves chrysanthemums and hates glory. He refused to bend over for Wudoumi and resigned from Pengze County Order. He likes drinking very much and never pursues wealth. He is willing to retire to the garden and grow beans in Nanshan. What a good teacher! In the middle of Yuanming Temple, there is a Yuanming statue carved with white marble, and on the right is his autobiography inscription "Drinking". These more than 30 paintings are based on the famous poet Tao Yuanming and introduce his life course in 6 1 year. Five times as an official, five times back home. Don't bend down to pick up five barrels of rice without it. After he resigned from pengze county at the age of 4 1, he was happy to be poor and lived in the countryside all his life.

The following is part of his biography of Teacher May 6th:

Relatives are still sad, others have been singing. What, is that how you die? From here, we seem to see that Tao Yuanming holds a very indifferent attitude towards the lofty festival, that is, he regards life as death and death as life.

Scholars such as Du Fu, Han Yu, Bai Juyi, Su Shi, Huang Tingjian, Zhu, Xin Qiji, Gu, Wang Fuzhi, Gong Zizhen, Liang Qichao and Lu Xun. Speak highly of him and show their admiration for him.

After Zhu Fang, go to Yuxian Bridge. This bridge used to be a natural boulder, lying on a stream, and it was called the place where fishermen met immortals. There is a couplet on the bridge: flowers hide immortals, why are they wandering, water attracts fish, and spring breeze does not come. It is written that the Peach Blossom Garden is hidden in Xianxi, which is a warm spring breeze and a fallen peach blossom creek, leading Wuling fishermen to such a mysterious and strange situation. Walk past Xianqiao, follow waterfalls and flowing springs, climb stairs, and come to Bai Yunxuan on the mountainside. Xuan and Baiyun will live together. It is also an interesting thing that the ancient trees in the back of the Xuan are towering into the sky, the Bitan Lake in the bottom of the Xuan is crystal clear, the bridges cross the lake and the white fog floats.

Through the mist, set foot on the ancient stone road, turn right through the rock, and you will arrive at the ancient cave of Qin people, who is said to be a native of Wuling fisherman. The ancient plaque Qin people's ancient cave is embedded in the mouth of the cave, and the mouth of the cave is half open.

It was narrow at first, but it was urgent. After a few steps, it suddenly became clear, giving people the feeling that the land is flat and the house is like that.

These antique houses are all villagers' houses. They have lived and multiplied in this paradise for generations, but they all know that there are Han people, regardless of Wei and Jin Dynasties. Interestingly, many people here are surnamed Qin, probably to avoid the chaos of Qin, so they take Chao as their surname. They are very hospitable. Every time the guests arrive, they will put wine and kill chickens for dinner and ask questions with salt.

Walk down the neat and quaint stone steps, and you will arrive in Chyi Chin first. Qin people's mansion s is the architectural style of Qin dynasty, with ancient windows and secluded walls, carved beams and painted buildings, cornices and corners, indoor furnishings full of pre-Qin flavor, and outdoor countryside full of mulberry and bamboo. Here, enjoy the wonderful couplets:

Suddenly there are 500 wonders, only the white clouds on the mountain are as pleasant; For this ancient and modern mystery, there is an uproar in Huang Qi.

It means that the Peach Blossom Garden suddenly opened a mysterious realm, like white clouds coming out of the cave unintentionally. It can make people feel nostalgic, make people feel happy and relieve their troubles. Here, I have made clear all the statements about the Peach Blossom Garden in ancient and modern times. Think of Huanggong Xia and Qili Chicken, the four heroes of Songshan Mountain at the end of Qin Dynasty, who came out to assist the Prince in his later years. It has too many desires. Only those who avoid the Qin people here are the real hermits.

Walking out of Qin's former residence is a bamboo gallery. Bamboo corridors are all made of bamboo, and the corridors and pavilions are connected, with exquisite structure and strange shape. Looking at the snake dragon in the distance, the momentum is extraordinary, the ancient meaning is wild and lifelike. Poetry couplets are hung high in the gallery, and all kinds of flowers and bamboos are planted on both sides. You can see the eyes of your life at a glance, and the vicissitudes of your life will last for thousands of years.

Unconsciously came to Friendship Hall, a classical wooden building with cloisters and buckets. It was built by Qin people, with a yard, a stage and a fish pond. Tang Chao is the gathering place of Qin people, where sacrifices, weddings and funerals, architecture and other major events are held.

Step out of the Chamber and step into the threshold of Fengxian Temple. Fengxian ancestral temple, as a ancestral temple for people to worship their ancestors, has been passed down to this day and has been rebuilt many times since. Today's ancestral temple, sparse windows and painted frames retain the original architectural style. Beside the temple garden, mulberry trees, under the temple, pavilions and pavilions, there are people everywhere. On festive occasions, weddings and funerals, Qin people worship their ancestors here. There is also the lingering sound of the Tang Dynasty, which is reflected in the bamboo shadow of Sang. Mulberry and bamboo were hidden in the middle of Tang and Zhou Dynasties, with dense ancient trees and beautiful scenery. Legend has it that lonely people without children

Changde itself is also an excellent tourist city in China, with rich tourist resources, including Taohuayuan, Xingde Mountain, Yiwangxi, Huayanxi, Wuyun Street, Jiashan Temple, Hu Ping, Taiyangshan, Shiqian, Liuye Lake and Hejie (Chuanzihe Scenic Belt).
