chinese dessert.

[msp4real]

Went to a Chinese restaurant today and received mystery dessert. It was a cold, milky soup with little bubbles (similar to, or possibly exactly, tapioca) in it. It tasted a little like the cucumber yogurt you de-flame Indian dishes with, but it was sweeter and self-sufficient as a dessert (ie, tasty). What is this?

Found! Sounds like it's called xi mi lu or sai mai lo. Thanks guys!
