What's the difference between folklore and custom?

Folk custom, that is, folk custom, refers to the life culture created, enjoyed and passed down by the broad masses of people in a country or nation. It originated from the needs of human social group life, and constantly formed, expanded and evolved in specific nationalities, times and regions, serving people's daily lives.

Custom is a behavior pattern or norm that people in the past dynasties followed in a specific social and cultural field. The diversity of customs is that people often refer to the differences in behavior norms caused by different natural conditions as "wind"; The difference in behavior rules caused by social and cultural differences is called "vulgarity". The so-called "different winds in a hundred miles, different customs in a thousand miles" precisely reflects the different characteristics of local customs. Custom is a social tradition. Some popular fashions, customs and inappropriate parts of the original customs will change with the changes of historical conditions. That's what the so-called "changing customs" means. Custom is a kind of historical formation, which has very strong behavioral constraints on members of society. Custom is the basis and supplementary part of social morality and law.
