Beef and mutton are fine to eat every two or three days, but if you want to eat them every day, you have to eat pork.

After eating, he asked someone to put the food in a big casserole and take it back home for his mother to taste.

Qin Shuyun tasted it, but didn't like the taste of the braised pork very much.

I feel too greasy.

However, I was quite surprised that the pork did not have any fishy smell.

After eating and drinking, Zhao Hao returned to his own courtyard to sleep.

I slept until night and was woken up by the cold.

“A-choo!”

Sitting up from the bed, Zhao Hao sneezed violently and immediately felt a chill.

He looked around and thought to himself, "It's just the beginning of winter and it's already so cold. How will I survive in deep winter?"

"No, we need some heating equipment."

"Oh, it's also useful in the school. Otherwise, I'm afraid I won't be able to attend classes properly in the winter."

"Also, it would be better to do something about the first floor, so that it won't affect business."

He did what he thought. After getting out of bed and washing up briefly, Zhao Hao lit the oil lamp and started writing and drawing on the desk.

There are two simplest types of heating equipment: a stove and a furnace tube.

Whether you burn coal or charcoal, it will be very simple.

It wouldn't be too difficult to make.

However, there is a disadvantage of the furnace.

It is suitable for use in a small space.

For example, in his current room, this is fine.

The school is also fine.

But, it doesn't work when it comes to the first floor.

The space is too large and I don’t know how many furnace tubes are needed to raise the temperature.

However, there is a way.
