When receiving an order from Amazon, most people throw away the packaging (包装材料) box, but one(Japan) man loves Amazon boxes so muchhe has spent the last 9 years collecting them.

    So what made a man take  collecting boxes as a hobby? For Kosuke Saito, it  (be) some numbers. It started one day in 2008. When Saito was openingAmazon box, he noticed(注意到) the serial number"XM06"  the box. He suddenly remembered seeing "MX08" on another Amazon box. He thought there must be an XM07 as well. He wanted (know) what that box was like. But it was only the(begin), because he soon found that Amazon boxes come in all(shape) and sizes, and he took a great interest in all of them. So far, Kosuke Saito has collected 77 different models used in Japan.

    However, one of (great) problems is that Saito's house is too small, so he has to rent(租用) a room for his collection.
