如果你相信这个行当的前景,熟悉它的规律,那么现在动手建一个送氧站,“换气”站正是时候。 小时候读过一篇科幻小说,说的是地球上的空气都被污染了,有个公司就把森林里的新鲜空气制成罐头出售,结果销路很好。没想到现在真的出现了这种行当,不过卖的不是空气而是氧气。相当于空气清新剂气雾罐大小的氧气罐,氧气浓度99.9％,可供半小时左右的呼吸。首次投入几十块钱,此后每次花4元钱换气,这样的氧气消费你接受吗?
If you believe in the prospect of this business and become familiar with its laws, it is time to build an oxygen station now. When I was a kid, I read a science fiction story, stating that the air on Earth was contaminated. A company sold the fresh air in the forest for canning and the result was very good. I did not expect that this kind of business really appeared now, but it was not air but oxygen. The equivalent of an air freshener aerosol tank oxygen tank, oxygen concentration 99.9% for about half an hour of breathing. For the first time put in dozens of dollars, then spend 4 yuan each time for ventilation, so you accept oxygen consumption?
