Pongal Harvest Festival
丰收节
...
Pongal is the harvest festival
dedicated to the sun god;
in Southern India the end of the harvest
it is observed as a 4 days festival called Pongal
...
It is like a Thanksgiving to the god for
the plentiful harvest received.
As I understand, it is a very big festival
in Southern India and the tradition
continues to be observed by the Indians in Malaysia
