Funny me? Two candles can also be used as heating

When it's hot summer, is it forgotten what the winter is? When the students in the south are frozen into an animal every year, the heated people in the north are always changing their superiors' sense of superiority, eating watermelons and making friends, and taking a look at the space for ice cream. It must be said that there is no gap between heating in the north and the south, which has become an important factor affecting China`s peace and stability. Compared to the expensive heating, the Southern School had a few years ago to rely on two flower pots and two candles to make self-made simple heaters, raising the temperature of a 10-square-meter room within 40 minutes at a very low cost.
