There are many rats in Lijiagou village. In the Tuyao cave of every family, the rats dig holes, chew boxes and bite cabinets, which makes the whole village suffer from. But at this time, there is a man named 'thief's eye', who comes to the village regularly to collect the rat skin. This makes Lijiagou people happy.

李家沟村老鼠多，每家每户的土窑洞里，老鼠挖窟窿眼开洞，啃小箱子咬柜，把村里人给坑苦了。可就在这时，有一个外号叫“贼眼”的，按时到农村来收鼠皮，这一下李家沟人可口可乐了。

There are five levels for the rat skin of 'thief's eye'. First level is 10 yuan, and each level is reduced by 虫草强肾王胶囊是治阴虚吗 2 yuan. The rat skin sold by people in the village is fourth class every time, with a piece of 4 yuan. But the only person who is the village director's daughter-in-law sold by second class every time.

贼眼收鼠皮分成五个级别，一等每一张10元，每差一等减2元。全村人卖得鼠皮，一直都是四等，一张4元，而唯有村主任媳妇儿卖得，回回全是二等。

There is a young man in the village. He is short, black and thin. But he is quick and flexible. No matter in the daytime or evening, if a mouse goes out of a hole, he can catch it. He is called 'the Mastermind'. But The mastermind is puzzled why does the mouse skin sold by the village director's wife cost twice as much as that of other families?

村中有一个年青人，偏矮黑瘦，身手敏捷，脑袋灵活，无论白天晚上，老鼠只需出洞，他准能逮到，人叫“神手”，可为什么村主任媳妇儿卖得老鼠皮比别家的贵一倍，神手疑惑。

This day, after selling the rat skin, he looked around and saw no one around. He asked the thief, 'what's the 吃虫草强肾王能长期使用吗 price difference between rats in the same village? Did you for the sake of the village director's face when you collect the mouse skin? '

这一天，神手卖光鼠皮，瞧瞧四下没有人，便问贼眼：“同为一个村的老鼠，价格咋差那么大？你收老鼠皮还看村主任的脸面？”

The 'thief eye' smiled and whispered, 'businessmen just look at the goods, they don't look at the officials.' He said and took out two pieces of rat skin, one of which was from the village director's house, and one of which was from the mastermind .

贼眼嘿嘿一笑，细声讲到：“商人验货不看脸，收鼠皮看毛不朋友。”他说道着取出二张鼠皮，一张是村主任家里的，一张是神手的 .

'Look against the sun yourself, and then touch it with your hand.' The master raised the mouse skin and saw that it was really moist and bright in the village director's house. His mouse skin was dry and dim. Once again, the former was slippery and greasy, while the latter was rough and stabbed. The master is sincerely convinced.

“你自己冲着太阳光看一下虫草强肾王是真药吗，再用手摸下。”神手抬起老鼠皮一瞧，村主任家里的果真盈润明亮，自身的那张老鼠皮变枯黯淡；再一摸，前面一种滑滑油腻感，后面一种不光滑扎手，神手赞不绝口。

After pondering for a few days, he thought of a trick. He put a little oil on 10 rat skins and rubbed them repeatedly with a soft cloth to make the skin shiny. This time, he thought, it would cost a good price! Who knows that the next day when selling rat skin, the thief's eye gave the lowest price, 2 yuan each.

揣摩了几天，神手想了个绝技。把少量小磨香油，涂到10张鼠皮上，又用一块软抹布不断磨擦，直擦得那鼠皮油亮闪耀，他想，这次还要卖个好价钱啦！没想到第二天卖鼠皮，贼眼却给了个最少等，每一张2元。

Looking at the angry hand, the thief's eye said: "my brother, please calm down. The quality of the fur color of the rat skin is that the rat usually eats and eats, not fakes." For example, can two people, one eating fish and meat, the other eating bran and vegetables, have the same complexion? The thief's eyes are right. He goes away with red face.

看见一脸怒火的神手，贼眼说：“老弟啊息怒，鼠皮虫草强肾王价格表背毛的好与坏，是老鼠平常吃东西吃出的，并不是造假做出来的英文。”又举例说，例如两人，一个吃鱼吃肉，一个吃糠咽菜，脸色能一样吗？贼眼讲得侃侃而谈，神手红了脸离开了。

After a few days, the thief eye came to collect the rat skin again. This time, all the villagers were shocked: the 10 masterpieces were first-class and sold for 100 yuan! Some people secretly ask what's wrong with the Mastermind. the Mastermind laughs but doesn't answer.

过了几天，贼眼又来收鼠皮，这次全村人统统大吃一惊：神手的10张全是一等，卖出去100元！有些人悄悄问神手咋回事儿，神手笑而不答。

A few days later, the thief's eye came to collect the rat skin again. This time, it's even more strange. Among the dozens of rat skin made by magic hand, the others are fourth class, There is only one. For the first time, a thief's eye has been set as a special grade, and 20 yuan has been given.

又过了几天，贼眼又来收鼠皮，此次更怪异，在神手的十几张鼠皮中，其他全是四等，

单单有一张，贼眼破天荒地列入特级，拿了20元。

The village director's daughter-in-law thought that there must be fraud in a rat skin sold for 20 yuan. In the evening, she told the village director. The village director didn't say a word. After a while, she said, "he didn't cheat."

神手一张鼠皮竟卖20元，村主任媳妇儿感觉在其中必然有鬼，夜里，她把这事告诉村主任，村主任听了没吱声，过了一会儿才说：“他没造假。”

"No fraud? Then how can they sell more expensive? "

“没造假？那咋能一次比一次销量贵？”

The village director told me truthfully:' the last ten mice were caught in the canteen of the township government by the Mastermind.'

村主任如实相告：“之前那10只老鼠，是神手在乡镇政府饭堂捉的。”

"What about today's?"

“那今天的啊？”

The village director said: "there is a mouse in the village head's house. It's been years since he can't catch it. I let him catch it yesterday."

村主任说：“乡镇长家有只老鼠，好几年了便是捉不了，是我昨天让神手去捉的。”
