枪怕圆，鞭怕直--to stab the spear curvedly and lash the whip straightly

武术界谚语-A proverb from Chinese Wushu

枪怕圆，鞭怕直：枪本是直着使的，如能使成圆，则显出枪速之快；鞭是软兵器，如能使的和枪一样直，必是内劲注于上。
 --to stab the spear curvedly and lash the whip straightly--
Despite the spear is straight and stiff, it is possible to make the spear curved. Stabbing the spear curvedly shows that how fast the user's action is.
The whip is soft and flexible, but one can also lash it to be straight. Lashing the whip straightly shows the holder's wonderful strength and technique.
