In the Chinese language class, Mr. Zhao explained: “The Chinese character 醋（for vinegar）is meaningful！
-------its left part looks like a jar with a nice lid and some liquid thing in it;
-------The top of its right part means “twenty’; The 日（the Sun) represents ‘one day’
-------The whole character could tell you how to brew vinegar!----------You put the raw materials into the jar and seal it with the good lid, and leave it aside alone；Twenty plus one days later，the special liquid would be produced!
(The above is one part of my recent blog ‘One bottle of vinegar for one month, please!”）---------Please have a look at it if you are free!
