Chinese Idiom：天衣无缝 (tiān yī wú fèng)
There was a man called Guo Han (guó hàn 郭翰) in the Tang Dynasty (táng cháo 唐朝,618-907AD). One summer night, when the moon was very bright, he suddenly saw a girl descending slowly from the sky. He observed the girl closely, ans found that the dress she was wearing was seamless. He was puzzled, and asked why. The girl answered, “Heavenly clothes are not sewn with needle and thread.”
This idiom is used metaphorically to indicate the flawless handling of things. It can also be used to indicate perfectly written poem or other literary article.
