(1) It is wrong to equate traditional customs with cultural backwardness.
(2) The so-called traditional customs refer to the relatively stable culture formed in the long-term historical development and preserved in real life. Cultural backwardness refers to all kinds of superstitious, ignorant, decadent and vulgar cultures.
(3) Cultural backwardness is usually manifested in the form of traditional customs, such as fortune-telling, fortune-telling, divination, geomantic omen, etc. However, cultural lag is not only manifested in traditional customs, but also not all cultural lag.
(4) China's traditional customs have both essence and dross accumulated by predecessors. On the basis of critical inheritance, we should keep the essence of traditional customs, transform backward parts and innovate.
This problem is an analytic problem. This paper mainly investigates the understanding of the differences and relations between "traditional customs" and "cultural lag". "Traditional customs" does not mean "cultural backwardness". There are both essence and dross in "traditional customs". "Cultural lag" is usually manifested in traditional customs, but not all of them are cultural lag.
