Most people think that Su Shi is free and easy,mainly influenced by Buddhism and Taoism.In fact,the principle of“Yi Jian”of Zhouyi,which was studied by Su Shi in his whole life,is also one of the important ideological roots.Under the revelation of the principle of“Yi Jian”of Zhouyi,Su Shi developed a careless attitude towards life,the simple and plain communication principle,the simple and cursory habit of daily life,thus enabling him to cope with all circumstances openmindedly,straightforward,adapting himself to different situations,showing a free and easy spirit.The principle of the life of Su Shi still has great reference significance to our current human beings.
