day 17 of a yin moon

Cast off what is obsolete or wrong, or not right for the coming times. Take away a skin or other outside that hinders life. Not all skins can grow, the one's who cannot have to be renewed when the time has come.
   It has to be done at the right time, when the old is on the point of breaking, and the new has the possibility to grow. Like the snake sheds his skin at the exact right moment. Sì-day is the day of the snake, the best possible day for skinning.

Initial 9 : Bind them using yellow cattle's hide.

This year, 2001, is a year of the snake. If you want to change something, this might be a good year for it...

Once you know the character Si (looks like an S) you can easily find all snake-days. A WanNianLi is cheap and it lasts about 100 years.
