Wheel
轮子（A-2-3-4-5顺子）
The wheel is the A-2-3-4-5 straight, which is the lowest possible straight. However, it can also be used as a high straight (TJQKA) in some game variations. In Texas Hold'em, it is always the low straight.
Example
With A-2-3-4-5, you have the wheel - a straight that can be vulnerable to higher straights.
