It is suggested to buy imported balloons on Taobao, because this kind of balloon is of good quality and positive color, which is far from domestic balls. Buy Colombian balloons, heart-shaped or round. The price of a ball is about one dollar.

Then, take the bought ball to the wedding company and fill it with helium. The price of helium is about 10 inch or 12 inch from 2 yuan to 3 yuan.

Since it is to decorate the wedding room, don't be afraid of trouble. After all, it is a surprise for my wife.
