Because Xu Ning has two sets of ancestral marksmanship, one is the golden spear method and the other is the hook and sickle spear method. These two sets of marksmanship rely on the eight-character formula "hook, dial, dig, hand over, save, divide, Fight, seize." From this point of view, it seems that the eight-character formula of "tripping, splitting, entangling, poking, picking, leading, sealing and turning" is a bit like the dog-beating stick method of the Beggar Gang. That's why it only took twenty rounds to kill Lu Shinang.
Xu Ning's golden spear technique is used to fight enemies in battle, while the hook and sickle spear technique is specially used to restrain chain horses. The functions of these two spear techniques are slightly different. The hook-and-scythe spear technique is unpredictable, and the Yanling Golden Armor is invulnerable. Xu Ning's hook-and-scythe spear is probably not a particularly sharp weapon. It's just that the marksmanship is quite different and the moves are rather weird. Not only can it be used to capture enemies on horseback, but it can also be used in infantry combat.
As the saying goes, things are rare but valuable. Xu Ning's two sets of marksmanship are inherited from his family and outsiders have no chance to learn them, so they are unique. Xu Ning has these two unique sets of marksmanship.
As for Xu Ning's marksmanship, Lin Chong, the instructor of the Forbidden Army in "Water Margin", commented: "This is Xu Ning's 'golden spear method' and 'hook and sickle spear method'" He is unique in the world." Lin Chong's martial arts in "Water Margin" is also considered to be one of the best. But he can give such a high evaluation of Xu Ning's marksmanship, which shows that Xu Ning's marksmanship is very powerful.
But I think Xu Ning is very skilled in martial arts and takes good care of his family. He just neglects to take care of his beloved things, and he doesn’t behave like a hero. He and Lin Chong were also considered colleagues as officials, and they admired each other and cherished each other as heroes. However, when Lin Chong was in such a big trouble, Xu Ning never drew his sword to help Lin Chong. He didn't even say a word of justice, which shows that Xu Ning is not a chivalrous and righteous man. All he sees is a harmonious and happy family.
Unfortunately, during the fight with Zhang Qing, he was the first one to appear. Unexpectedly, Zhang Qing was very good at concealed weapons. He was hit by a stone in the face and fell from his horse. Later, on the way to conquer Fangla, he attacked Beimen Pass in Hangzhou and was hit by a medicinal arrow in his neck. Treatment for half a month was ineffective and he died of illness in Xiuzhou.
