乐广在家中思来想去、东翻西找，最后在客厅一抬头便看见墙上挂了一只弓，弯弯曲曲地像条蛇似的。脑中突然灵光一闪，心想：该不会和这只弓有关吧？于是乐广发挥了科学办案的精神，决定来个案情重组。

Yue Guang racked his brain and searched everywhere at his place. Finally, he looked up in the living room and saw a bow hanging on the wall. The bow looks twisted like a snake. A light bulb went on in his brain, "Could the bow has something to do with this?" He thought. Then he decided to reorganise the case with the spirit of tackling this case using science.
