From the north side of Gushan Temple to the west side of Jiating, the lake is just level with the embankment, with low clouds and waves on the lake. Several early orioles raced to the sunny tree, and their new swallows were carrying mud in their nests. Colorful spring flowers will gradually fascinate people's eyes, and shallow spring grass can barely cover the horseshoe. I love the beauty on the east bank of the West Lake, and I can't get enough of it, especially the white sand embankment under the green poplar.

Bai Causeway starts from Broken Bridge in the east and ends at Autumn Moon in Pinghu, the southern foot of Gushan Mountain in the west, with a total length of about one kilometer. It divides the West Lake into an inner lake and an outer lake. Walking along the embankment, you can fully enjoy the beautiful scenery of the West Lake. When Bai Causeway is mentioned now, people will naturally associate it with Bai Juyi's name, and some people think that Bai Causeway was built by Bai Juyi.

In fact, Bai Causeway existed long before Bai Juyi came to Hangzhou to be in power, and it was called Baishadi at that time. It is impossible to find out when it was built and who presided over it. Bai Juyi led the construction of Baigong Dike instead of Bai Causeway. Bai Juyi served as the secretariat of Hangzhou for three years. In this short time, Bai Gong has done many great things for Hangzhou, which is of great significance to the development of Hangzhou.

Before Bai Juyi went to the West Lake, the West Lake was not fundamentally rectified. In dry weather, the West Lake is shallow enough to irrigate farmland, and drinking water for residents is also a big problem. Every time it rains heavily, the lake will flood again, and you can't save it. This situation makes the West Lake unable to exert its maximum utility, leading to problems in both agricultural and civil water sources.

In October of the second year of Changqing, Bai Juyi came to Hangzhou with the ambition of "being close to the people". After taking office, I put the project of thoroughly managing the West Lake on the agenda. One of his main achievements as the secretariat of Hangzhou was to build a large-scale lake protection platform along the northeast bank of the West Lake, which effectively stored water and discharged floods, ensuring that farmland was irrigated with water and people had water to drink.

The construction of dams and water storage lakes was completed two months before Bai Juyi left office. In March, 824, Bai Juyi personally wrote the article "Stone Story of Qiantang Lake", carved it into a stone tablet and stood on the shore of the lake. This inscription has become an important historical document of West Lake water conservancy. Bai Juyi's Lake Tower is called "Baigong Dike", which expresses his love for Bai Juyi.
