This is a popular dessert item among Chinese, and is one of my favourite dessert of all.

Traditional Chinese believe that food are broadly categorised as yin 阴(cooling), yang 阳 (warming) or neutral. For example, eating “warm” food generates warmth in the body whereas eating “cooling” food makes the body feel cold.
Whether to eat warming or cooling food depends on the time of the year and our bodies current state of imbalance. This is the concept of balancing the Yin and Yang, very much a part of our Chinese culture.
This dessert has “cooling” properties, consuming it can tamper the “heat” in our bodies. Especially after eating “heaty” food such as deep-fried food or when the weather is hot.
Smooth and silky, and mildly sweet, this dessert can be served hot or chilled.
