What is the answer to the sentence "before writing"?

Today, the weather is very good. The teacher and we played a game in the classroom. The name of this game is "guessing riddles". I am very excited, because I am not bad in solve riddles on the lanterns!

The teacher announces the rules, boys and girls fight, and the winner gets extra points. Just hearing this rule, my blood boiled and I shouted "Boys will win"!

The game started, and my heart was in my throat. I saw the teacher pick up the chalk and write "fifteen days, (type a word)" on the blackboard. I was dumbfounded when I saw it. It turned out to be another riddle, and I fell! I guess: "Fat, but I'm not sure". Chen Chen raised his hand over his head and twisted his ass impatiently from time to time. Xu Li have answers, seems to be a shoo-in. Suddenly, the teacher asked Xie Fei to answer, and Xie Fei said confidently, "It's fat." The teacher said, "Why?" Xie Fei said: "Because fifteen days is half a month, and you will gain weight in half a month." The teacher gave Xie Fei a thumbs-up sign, and we boys said unconvinced, "Why do you choose girls?"? We boys haven't chosen yet ... "

Then, the teacher wrote "imperial edict (type a word)" on the blackboard. As soon as the teacher finished writing, Bao asked Yu to say, "It's Weng". The teacher shook his hand, and the two people behind him were so unlucky. I thought about it and gave a hard knock on the head with my pen. At this time, the teacher gave a hint: the imperial edict is the order issued by the emperor and the king. However, we still don't know. Suddenly, Xu Li raised his right hand and the teacher asked him to answer. Xu Li said unhurriedly, "It's Ling". The teacher said, "That's right." As he spoke, he made a heavy tick behind Ling. Xu Li is really our life-saving hero and won us a precious point.

Then, the teacher asked a lot of questions. Finally, the boys won the game 4: 3, and we boys cheered for joy, because in the past, many games were won by girls, but this time it miraculously turned the tables!

Solve riddles on the lanterns games not only add happiness to us, but also exercise our brain's thinking ability. It's killing two birds with one stone!
