In "Ngu Kin Hang" or "the snake-bites-tail game", there are two teams - a mother snake (including her babies) and a father snake one-man team. Mother and father snakes are engaged in a preliminary dialogue which goes something like this:
Father snake: Dear Mother Snake. Mother snake: Yes, Father Snake. Father snake: From which well do you drink? Mother snake. I drink from a well in the stone. Mother and babysnakes in chorus: Each one of us does too.
(The line of baby snakes then sways from side to side.)
The question and answer rhymes go on for quite a while but it all boils down to which part the father snake will eat the mother snake's middle part or her tail both comprising baby snakes. In the end the father snake will try to catch any of the little ones behind the mother snake's back. She, of course, must try to protect them.
