缂丝最难的地方在于技法，尤其是嵌色过渡颜色的技艺。很多线的颜色都是由两个色系组成，都是组合色。和绘画一样，要先调色，缂丝是用丝线调色。色系越多，花费的时间越长。Technically, the most difficult thing about kesi is the transition colors in the mosaic artworks. If you look closely, those are combined colors. It’s just like painting. In dyeing, you mix the colors first with the yarns. The more the colors, the longer it takes. #缂丝# #CGTN传承中国#

天干地支（Chinese Era）

The Chinese era is the symbol that the Chinese calendar uses for recording and naming years. The ten Heavenly Stems are: jia, yi, bing, ding, wu, ji, geng, xin, ren, gui. The twelve Earthly Branches are: zi.chou, yin, mou, chen, si, wu, wei, shen, you, xu, hai. After observing the lunar month, the ancients found that the moon always wazes and wanes roughly 12 times a year, and two lunar months account for about 60 days, so the order of the ten Heavenly Stems and the order of the twelve Earthly Branches are properly matched in turn. In terms of recording date, 60 years is considered to be a full time cycle. The Chinese era chronology was first invented in ancient times and is still in use now.

天干地支是中国历法中用以记录和命名年岁的方法。十天干为：甲、乙、丙、丁、戊、已、庚、辛、壬、癸；十二地支为：子、丑、寅、卯、辰、巳、午、未、申、酉、戊、亥。古人观测朔望月，发现月亮圆缺12次大体上是一年的天数，而两个朔望月约是60天。古人以十天干与十二地支的顺序依次相配，记录不同年份，60年为一个轮回。干支纪年法从古沿用至今。
