The middle pavilion is the surviving Ke Pavilion, located to the north of Hanbi Mountain House. Looking south from the pavilion, the "Hanbishan House" and "Mingse Tower" look like a ship, anchored by the water. The entire group of buildings breaks the neat and uniform layout, giving people a feeling of change and beauty and nature, reflecting the traditional technique of Chinese landscape painting in which the main scene is left to the right. Ke Pavilion has six corners and pointed eaves. It was called "Gezhong Pavilion" in Liu Shu's time, and later "Ke Pavilion" in Shengkang. There are many couplets in the pavilion, one of which is:
Autumn is the best time for the garden in ancient times;
The pavilion is as small as the mountains.
The couplet is signed: "Zheng Wenyuan inscribed the title of Liuyuan Keting". There is another part of Zheng Wenyuan's title couplet:
The garden is the best in the world, and it is Pengze's fun to see people in the lower reaches of Wu, carrying wine, carrying harp and Japanese instruments; Read Fu Weng's poems with stacked rocks and scenery.
The signature of this couplet is: "Zheng Wenyuan inscribed the Liuyuan Half Wild Cottage".
This couplet was later hung in Keting. Peng Ze in the couplet refers to Tao Yuanming, a writer of the Eastern Jin Dynasty. Tao Yuanming once served as Peng Zeling and was called "Tao Pengze" in his later life. Fu Weng refers to Huang Tingjian, a poet of the Northern Song Dynasty. Huang Tingjian was once banished to Fuzhou and named himself "Fu Weng".
The first couplet of this couplet praises the beauty of Suzhou gardens, the abundance of tourists, and the elegance of taste. Tao Yuanming, quoted in the couplet, shows a leisurely and elegant taste in life. The second couplet narrates the author's travels and praises the beautiful scenery of sparse springs and stacked rocks. The couplet combines the beauty of gardens and landscapes with Huang Tingjian's landscape poems. The beautiful scenery and poems complement each other and are evocative. But the third couplet in the pavilion is:
The water turns to Tongxi River to meet the autumn wind;
The road is looking for flowers and the steps are for spring outing.
The couplet is inscribed: "Anonymous Title Liuyuan Keting".
The "Autumn Harvest" in the couplet refers to the ancient people's pilgrimage to the water on the 14th day of the seventh lunar month to clear away the unknown, which is called "Autumn Harvest". The flower steps in the couplet are also called "Huabu Xiaozhu".
The fourth couplet at the pavilion is:
It is only up to me to advance in virtue and cultivate learning;
From kindness to peace, it is a joy. God knows.
The couplet is signed: "Yu Yue inscribed the title of Liu Yuan Ke Pavilion". Yu Yue was a famous writer, educator and calligrapher in the late Qing Dynasty. He wrote tirelessly throughout his life, and his main works include "Chun Zaitang Complete Book", "Xiaofumei Gossip", "Youtai Xianguan Notes", "Cha Xiangshi Miscellaneous Notes", etc.
Yu Yue was once a good friend of Sheng Kang, the owner of the Liuyuan Garden. Compared with Sheng Kang, Yu Yue seemed not very proud of his official career, but he left officialdom to concentrate on his studies and achieved great results. In this couplet, people can see the lofty qualities of a generation of Chinese masters in studying and cultivating morality.
There is only a pool between the rockery at Keting and the "Hanbi Mountain House", forming a north-south view. There are two ancient ginkgo trees next to the rockery. The crowns of the trees are connected and the trees are shaded from the sun.
