Beijing.

The dreary sky shrouded the land like a vast and incomparably bitter sea purgatory; The cold wind howled, so that the pedestrians on the roads in the capital couldn't help but wrap their clothes tightly and speed up their pace.

Uncle Zhang hurriedly walked to his home with the newly purchased honeycomb coal stove and honeycomb coal, the weather was too cold, the clothes on his body really couldn't resist the cold north wind, and the family was still waiting for him to buy firewood and go back to cook.

"Where's the firewood?"

When he got home, Uncle Zhang's wife, Zhang Xie, looked at Uncle Zhang, and hurriedly asked, the only grandson was already hungry, and he was already clamoring to eat.

"The price of firewood has risen again, and once the firewood costs more than 300 yuan, I can't afford to use it at all."

Uncle Zhang sighed, the year before last, his son suddenly fell ill and died, leaving a grandson, counting the daughter-in-law, the life of a family of four can be imagined, usually Uncle Zhang lives by selling pancakes, and his wife and daughter-in-law earn a meager income to subsidize the family by washing clothes, and the life is tight.

Because it is a pancake business, the price of firewood and grain has a great impact on Uncle Zhang's family, and the price of firewood continues to rise, making the already difficult days even more sad.

"300 Wen, why don't they rob the money~"

When my wife heard this, she couldn't help but scream, this price is too expensive, you must know that in normal times, once the firewood is only more than 100 yuan, I didn't expect it to rise to 300 yuan now.

"The price of charcoal is more expensive, and now the cheapest broken charcoal has risen to 600 Wen, and if this continues, we ordinary people will freeze to death."

Uncle Zhang shook his head and then pointed to the coal stove and honeycomb coal he picked and said: "But this time, we don't have to worry, I met someone selling this honeycomb coal on the street, a honeycomb coal is only 2 yuan, I heard the merchant say, it is still very durable, I don't know if it's true." ”

"2 yuan a piece, how expensive it is, how big it is, how long can it burn, you shouldn't have been deceived, right?"

When my wife heard this, she immediately looked at the coal stove and honeycomb coal carefully, and wondered if Uncle Zhang had been deceived.

"Probably not, that store is open, if it's really a lie, we can still go to them."

Uncle Zhang thought about it and said, in fact, he was also very worried about this, but there was no way, the current firewood was too expensive, and he couldn't afford it at all.

Such a cheap and easy-to-use thing, no matter what, you have to give it a try, if it really works, then you can have a lot of expenses left in the future.

"How do you use this honeycomb coal?"

My wife asked, looking at the honeycomb coal, and then at the strange coal stove.

"It's simple, first burn a few pieces of honeycomb coal, then put the red-hot honeycomb coal at the bottom, and then add honeycomb coal to the top."

Uncle Zhang just watched it once, but he was not unfamiliar at all when he used it, and soon used the remaining firewood at home to burn 3 pieces of honeycomb coal, put them into the coal stove, and then added a few pieces of honeycomb coal, and fanned the wind here.

It didn't take long for the honeycomb coal in the coal stove to burn, and the heat was huge, and Uncle Zhang couldn't help but stretch out his hands to roast and warm the fire on the coal stove.

"The heat of this honeycomb coal is still very good, it is as warm as charcoal, or even warmer."

Uncle Zhang felt it carefully and nodded in affirmation.

"It's really pretty good, it looks like this honeycomb coal is quite resistant to burning."

My wife also nodded, then took out the pot, put the pot on the coal stove, and found that the size was just right, very suitable.

"Don't say it, it's a decent size."

Uncle Zhang's wife was also afraid that the honeycomb coal would burn too quickly, so she hurriedly added water to the pot, and then began to mix noodles and prepare to make a bowl of noodles for the family.

The firepower of honeycomb coal is very sufficient, and soon the water will be boiled, and a meal of pasta will be out of the pot quickly, Uncle Zhang moved the pot away, looked at the honeycomb coal that was still full of vitality, and couldn't help but smile: "This honeycomb coal is really good, quite durable." ”

Then he closed the lid on the opening, and soon the coal in the furnace did not have enough oxygen, and the combustion gradually became smaller, until at last only a small, small fire remained.

At night, Uncle Zhang's grandson kept saying that his body was itchy, and Uncle Zhang also used honeycomb coal to boil water for his grandson again and took a hot bath, and then moved the stove into the room to warm it for a while.

The next morning, Uncle Zhang opened the opening again, and with the instigation of the fan, oxygen continued to enter the coal stove, and soon the coal stove was burning again.

Cooking for breakfast, the fire in the coal stove is still very strong, and Uncle Zhang also began to use this honeycomb coal to start baking cakes to prepare for today's business.

"The bottom honeycomb coal has finally burned out~ It's really durable, easy to use, and the key is cheap."

It wasn't until Uncle Zhang finished baking all the pancakes that needed to be shot in the morning, he carefully checked the situation in the coal furnace, and took out the honeycomb coal at the bottom, and the original black honeycomb coal turned into a ball of yellow mud, which broke when he touched it, just like what the shopkeeper said.

"Uncle Zhang, I heard that you bought that new type of honeycomb coal yesterday, is it good to use?"

Uncle Zhang walked down the street with his freshly baked pancakes, and the neighbors hurriedly asked.

"It's easy to use, it's very good, don't look at a small piece of honeycomb coal, it's very burn-resistant, I bought it yesterday and have been using it until now, and it doesn't cost a few pennies in total."

Uncle Zhang naturally nodded again and again, giving honeycomb coal a high evaluation.

They are all neighbors, everyone's life is actually about the same, and it is very difficult in winter, with this cheap and durable honeycomb coal, it is natural that it will not be hidden.

Uncle Zhang is like a mobile advertisement, he will say good things about honeycomb coal, and soon, the people around Uncle Zhang all know about honeycomb coal, and they all rushed to the store of Xishan Coal Industry in Chongnanfang, Langdong, ready to buy some honeycomb coal and try it back.

People are like this, the words of strangers are always not very credible and suspicious, but the people around them and familiar people are naturally more believable.

Of course, this honeycomb coal is really easy to use, and it is also really cheap, a piece of honeycomb coal is only 2 yuan, and a family can't use much if it's just cooking.

Therefore, the best advertisement is the word of mouth of the people, and under the word of mouth, honeycomb coal began to spread throughout Beijing the next day.
