Etiquette,li,comes from the fear and respect of the nature in China.

中国人对礼的认知首先来自于对大自然的敬畏。

We find all the forms of li from heaven,earth and nature.

天、地、自然万物，从中我们发现了秩序，也找到了礼的格式。

Li represents the authority of emperors who was given by heaven.

礼在官方，体现了皇权天授的威严。

Li also represents hierarchy. In social life,li means that people get along with each other harmoniously and respect the elderly.

礼也体现了等级。礼在民间，人们和谐相处，长幼有序。

Li comes from the heart of people,showing respect to heaven,the earth and people is important.

发自内心的礼，在规矩之上，是中国人对天、地、人的敬重。
