What is hotel renewal?

In his later years, after dinner one day, Gan Long called Ji Xiaolan, a college student. They put on casual clothes, walked out of the palace and wandered in Chengde Street. I saw a hotel sign that said "semi-joint venture hotel". If there is a market in front of the store, it will be crowded. The two stopped, only to hear the shopkeeper's hand shouting, "Thank you for your attention. There is half a couplet in the shop. Who can continue the couplets and use all the delicious food? I have to give 10 two. " The two men were curious, so they went into the shop and saw the half couplet hanging in the middle of the room:

A string of scaleless short-lived eels with long catfish mouths.

The monarch and the minister pondered for a long time, but they couldn't find a suitable bottom allied. Just then, the hotel guy came in with a basket of big crabs. One of them is a huge fish, which is kicking around on its back. Ji Xiaolan had a brainwave and sang the bottom allied:

Three yuan has armor, turtle round turtle flat crab short head.

This couplet is unique and interesting, with neat words. With three strings, there is a pair of scales. Turtle circle is the abbreviation of loach, turtle flat is the length of eel, and crab short head is the mouth of catfish, which can be described as seamless.
