Yeah, I have heard about this beautiful folktale since childhood. China still celebrates it on the 7th day of 7th month(with the Chinese lunar calender) , so it can fall on the different date of the Western calender every year. Now in China Double-Seventh Day(Tanabata) is equal to the Western Valentine's Day specially for lovers, but it is said that in ancient China, it was also for young girls to be proficient in weaving.

Legend has it that on each Double-Seventh Day the magpies fly together to form a bridge across the Milky Way, helping Orihime and Hikoboshi meet each other. In my local place, it is entering the rainy season(the point from Summer to Autumn). When we hear the sound of showers in that night, we just say that it is the sound of their weeping.

At the same time, I love Bashō's Haiku. It is so wonderful to associate the wild sea towards Sado Island with the insurmountable Milky Way in heaven.
Below is a video of its Chinese version I find on Youtube with English subtitles.
