does anyone here know a chinese river whose name starts with an 'S'?
We are starting a new IC project. Since I am leading it, I have the privilidge to pick a name for the product. Our products are always named after a river, so this time I'd like to pick a river in china to name it. It has to start with an 'S' due to another companion product. But I could n't think of any. please help me, I really want to promote something related with china in this company.

oh.. song hua jiang (Sungari) can't be used because it was used before.
