本论通过日本出土的一种叫“埴轮”的陪葬品中人偶的服饰和古墓壁画人物的衣饰情况结合文献对日本历史上存在的贯头衣和左祍现象进行分析,将其与现存于苗族服饰中的贯头衣和左祍现象进行对比,探讨现存的苗族服饰文化并非现在人们所讲的隋唐服饰习惯,而应该是先秦时代甚至更早的服饰文化。同时也对苗日两民族的文化在历史上是否有直接接触做了探索并提出自己的意见。 Based on the analysis of clothing and the appearance of ancient tombs and murals in a kind of funerary object named “埴 埴” unearthed in Japan, It is compared with the traditional clothing and Zuojiao existing in the Miao costumes to explore the existing Miao clothing culture is not what people now talk about the clothing habits of Sui and Tang Dynasties, but rather should be the pre-Qin era and even earlier clothing culture. At the same time, we also explored whether there is any direct contact between the cultures of the two peoples in Miao and Japan and put forward our own opinions.
