Ya 'an, the rainy capital, is elegant and safe. The Qingyi River, which originated from Jin Jia Mountain and Erlang Mountain, passes through the city from west to east, and after thousands of turns, it joins the Minjiang River at the foot of Leshan Giant Buddha and finally enters the sea.

The surging river not only provides a material basis for the development of human beings along the coast, but also brings aura to the ancient city of Ya 'an. Three rivers meet, eight bridges are vertical and horizontal, and ancient banyan trees are shaded. Xiao Ya 'an not only inherits the ancient civilization, but also connects the plateau and the basin. It is not only a place where merchants gather, but also a traffic fortress leading to Tibet and Yunnan. It is also the area with the most complete cultural protection in China and the starting point of the famous ancient tea-horse road. The Han Tombs and ancient Tea and Horse Department scattered along the roadside in Shan Ye (the ancient tea-horse business institutions) seem ordinary, but they bear a very heavy cultural history.

Ya 'an's unique natural geographical environment and humanistic environment have given birth to Ya 'an's "three musts"-Yayu, Yayu and Yayu. Of the three wonders, Yayu is the most distinctive. Rainy days (in Ya 'an, there are always many such days. According to statistics, there are as many rainy days as 180 days in Ya 'an, with an average annual rainfall of 1800 mm). The whole city is bathed in countless ways, and colorful umbrella flowers bloom on the wet streets, making you feel out of date.

The reason why Ya 'an is called "the sky leaks" is actually caused by its special geographical environment. To the west of Ya 'an is the Qinghai-Tibet Plateau, known as the roof of the world, and to the east is the Sichuan Basin, thousands of miles away. Ya 'an is located between these two completely different landforms, and is often influenced by the interaction of warm and humid airflow from the plateau and the basin. Coupled with a large number of warm and humid air currents from the Indian Ocean, they are often forced to move eastward around the plateau and enter Ya 'an, so rain clouds often gather here. At the same time, because Ya 'an is sandwiched between Erlang Mountain, Jin Jia Mountain and Daxiangling Mountain, and there is only one exit to the east, this "trumpet-shaped" terrain causes warm and humid airflow to enter only at night.

Ya 'an is the starting point of the ancient tea-horse road. Tea is an essential drink for herders on the plateau, but tea is not produced on the plateau, and horses are an important military supplies of the Han nationality, so the ancient trade of exchanging tea for horses came into being and gradually became an extremely important "survival trade" between the two sides. Ya 'an is famous for its warm, humid and rainy climate. Mengding Mountain, located 10 km east of Ya 'an, was famous for producing tribute tea in Han Dynasty. Li Bai's phrase "the water of the Yangtze River, the camellia of Mengding Mountain" frequently appears in every corner of Ya 'an.

In fact, Ya 'an has a lot to say, such as Baoxing, the place where the first giant panda was found, the Jin Jia Mountains, Anshunchang, the place where Wing King was buried, and the place where the Red Army won the battle. You'd better savor it yourself!
