On May 22, 1935, commander Liu Bocheng and political commissar Nie Rongzhen of the advance force of the Chinese workers' and peasants' Red Army met Xiao Yoda (xiaoyedan), the leader of the Guoji family of the Yi nationality, at the seaside of Yi nationality. They exchanged water for wine and swore to be brothers to make the brigade pass through Baili Yi area smoothly.
In July 1980, the people's Government of Sichuan Province announced that the Yihai Alliance Office was a cultural relic protection unit in Sichuan Province, and a marble cultural relic symbol was erected by the lake.
In 1995, it was officially listed as a provincial scenic spot.

Yihai lake is an alpine freshwater lake with an altitude of 2280 meters. The climate is warm and cool. The annual average temperature is 9-15 ℃. The four seasons are sunny and sunny. Yihai lake was formed in the early Holocene, about 15000 years ago. It was formed on the debris flow alluvial fan because of abundant groundwater recharge. Haizi is in the shape of Yuanbao. It is large in the South and small in the north. There is a water outlet at the south end. There is no water flowing around. It covers an area of 233 mu. The average water depth is 9.8 meters, and the deepest depth is 15 meters. It is a high mountain deep-water lake.
It is crystal clear all the year round, as clear as a mirror. From the perspective of Lake development, the Yi sea is in the stage of youth development. The Yi sea is surrounded by verdant pines, numerous trees, grass covered land, various kinds of mountain flowers competing for fragrance and beauty, and there are flocks of wild ducks on the lake. The overall landscape is vigorous and harmonious. At the same time, the historical story of the world-famous "Yi sea alliance" took place here. Beside the lake, there are Yi sea memorial halls and monuments to show people the historical chapters of the long march of the Chinese workers' and peasants' Red Army. The mountains and trees are particularly bright and fresh. Looking down from a height, Haizi looks like a sapphire inlaid in the mountains, glittering and translucent. Haizi is surrounded by ancient trees and fragrant grass. Rhododendrons, lilacs and Camellia vie for splendor. In the lake, flocks of wild ducks flutter and chirp, and play with the water. Strolling along the sea is like melting into the ink of the brush peak in the ink painting, which makes people daydream, relaxed and happy. Yihai has a cultural relics protection and management office, a lookout tower at the top of the mountain, cruise ships in the lake, reception rooms, pavilions, toilets and other facilities beside the lake, as well as a wild drinking area.
The Red Army advance team entered the Yi sea area on May 22, 1935. At that time, the Yi people were deeply estranged from the Han nationality because they were discriminated and oppressed by the Kuomintang's policy of ethnic discrimination for a long time. When the Red Army's engineering platoon entered the Yi sea area, they were attacked and 'harassed' by Yi people from time to time. However, the Red Army never fired a single shot, but kept on giving propaganda and explanation to the Yi people. However, the two sides did not speak the same language, so it was useless for the Red Army to explain. Finally, the clothes of the Red Army soldiers were stripped off by the Yi people.
Xiao Hua of the Red Army's advance team found a grandfather named shamayiku, hoping that his grandfather would convey the Red Army's goodwill to xiaoyedan: first, the Red Army is only a way out, and will never invade the Yi people; second, the Red Army advocates national equality. Seeing that the Red Army was a good army, shamayi's grandfather gave Xiao Hua an idea that there was a way to gain the trust of the Yi people, that is, to make brothers with our leader. But when samayi's grandfather went back to report to xiaoyedan, xiaoyedan couldn't believe it. If there is any problem, I can take the head guarantee! In this way, Xiaoye Dan agreed to meet with Liu Bocheng to discuss an alliance. "
So Xiaoye Dan went to see Liu Bocheng with my grandfather. When he saw Liu Bocheng, Xiaoye Dan quickly took off his hat and knelt down to kowtow. Liu Bocheng saw it and quickly met him. He helped Xiaoye Dan up and said, "we are brothers. We are equal. We are not interested in this set of things." Xiao Yedan was very moved. He said that before seeing the officers of the Kuomintang, they all had to kneel down. It seems that the Red Army and the Kuomintang troops are really different. After a frank and friendly conversation, the two sides decided to pledge blood and form brothers. Samayi's grandfather immediately found a big rooster, but could not find the wine. Liu Bocheng said that as long as everyone is sincere, it doesn't matter whether there is wine or not. Then he took off the military kettle on his waist and asked the guards to fill the lake water in the Yi sea and pour it into two large bowls. Samayi's grandfather killed the rooster and dropped the blood into the bowl. After the ceremony was ready, the two knelt down side by side, took up the "blood wine" and swore to the blue sky and the Yi Hai alliance.
In this way, the Yi people and the Red Army became a family. On behalf of the Red Army, Liu Bocheng also presented some weapons, ammunition and a flag with the words "Guji detachment of the Chinese Yi People's Red Army" to Xiao Yedan, formally establishing the Yi People's detachment of the Chinese Red Army. After the Red Army left, the Kuomintang troops came, and they took away the guns that the Red Army gave xiaoyedan. And that flag was sewn in the pleats by xiaoyedan's wife.
After liberation, Xiao Yedan's wife dedicated the team flag that had been preserved for more than ten years to the army of the liberation of the Yi sea. This flag is also kept in the Chinese people's Revolutionary Military Museum! ""。
