Chinese Blackjack is also known as 21-point, ban-luck (Hokkien), ban-nag (Cantonese), and x dch (Vietnamese). The game is played in South East Asia and resembles conventional Blackjack.
In fact, the value 16 is said to be the worst hand one can have in blackjack. Since sixteen of the other fifty cards have a value of 10 and four have a value of 11, there is a strong chance of getting at least an 18 with either or both split cards. A hand totaling 18 or 19 is much stronger than having a 16.
