Why is red the traditional color of the Chinese nation? Which dynasty did it begin in?

Legend has it that in ancient times there was a monster named Nian who would come out to eat people in 360 days. People didn't dare to offend him, so they gave him a tribute, just a child. I chose a mother as a tribute to fight the monster. It happened that the sage passed by and pointed out the maze, saying that you were afraid of the explosion when bamboo burned and red. When you come to "Nian", you are asked to put red things (stained with blood) on every household. In order to celebrate in the future, people will do it every 365 days, and it will gradually become the New Year, and red, which played a huge role in this event, has also become the traditional color of China people! Specific to the dynasty, roughly more than 100 years earlier than the Xia Dynasty!
