Yu Yin is mute, but he is very cheerful. In his opinion, everything has a good side. But when he was 15 years old, his parents died in a car accident. His uncle was supposed to raise him according to his will, but because he was afraid of trouble, he left him to his "dumb" son Gu Liang. Gu Liang didn't like to talk since he was a child. Later, he left his parents and learned sign language, and he never opened his mouth to speak again. Gu Liang was only 18 years old at the time. He was forced to drop out of school because of his withdrawn personality and his inability to communicate normally with others. After dropping out, he moved to the small county of Hechuan to live alone. Gu Liang is an artist who has studied photography. He makes a little money from his pretty good paintings and photography. The two brothers can buy what they like regardless of the price. Yu Yin's grades are good. He writes very well. Without special training in writing, he can see the essence through phenomena and express it in words. English is also his strong point. They have been together day and night for 5 years and have brought each other into their lives. No one can live without the other. When Yu Yin became an adult, he would write next to Gu Liang when he was painting or taking photos. Later, it was posted online by netizens and was named The Story of Two Mute Immortals. When Gu Liang's father found out about it, he knew that they had made a lot of money and wanted to take them back to his hometown. The two disagreed. The father was so angry that he made up rumors about the two of them on the Internet. As a result, the two refused to give up their lives. Despite facing bankruptcy, he still managed to make money. In the end, hard work pays off.
