When it was rain, it was as if the wind was leaking from everywhere, and it was so cold that there was nowhere to stay.

Zhang Fangyuan was afraid that Xu He would be cold, so he went to the street and bought a hand warmer, and filled it with hot water from the restaurant for him to hold.

"You need this in the early spring?"

"You can't be cold."

Xu He's mouth twitched, and he held the hand warmer, feeling warm in his heart: "Fortunately, no one at home came to see our opening today, otherwise we will make them anxious."

Zhang Fangyuan's mentality was quite good: "Business is not a one-day success, and you can't do anything in a hurry."

Xu He nodded, but in fact, he had no idea. The cost of opening the toothbrush shop this time was not a small sum. He had been calculating the rent of the shop, the pre-installation, and they had spent fifty taels of silver until the shop opened today.

"Then, can we have business today?"

Before Zhang Fangyuan had time to reply Xu He's pitiful words, two young man walked in together. He patted Xu He's hand and said in a low voice: " What do you say?"

After speaking, he got up to greet the visitor.

"Several guests are free to take a look. If there is anything that needs to be introduced, just call me."

The two scholars held folding fans, nodded to Zhang Fangyuan, and wandered around the shop. The small shop was not big, there were no upstairs or downstairs, just a single shop that could be seen at a glance. Although the place was not big, there were many things.

Upon entering the door, there was a long waist-length display cabinet, extending all the way to the end of the shop, with evenly distributed small grids in between, among which were all small porcelain bottles that looked like spices and powder. In addition, there was another standing cabinet, inside which were two-inch long index finger-thickness small brushes with fine bristles on the head.

Although there was no other shop like this in the city, a few scholars still recognized at a glance that the tools on the cabinet against the wall were used for brushing teeth.

"May I take two out for us to take a look?"

Zhang Fangyuan heard that and he took three out from the cabinet for the scholars. In fact, the toothbrushes on display were for customers to experience, and those who wanted to buy would be picked up separately.

"The softness of these bristles are not the same."

"Exactly, the hairs used are different." While explaining, Zhang Fangyuan took out a jar of the cheapest chinese honey locust tooth powder from the cabinet, and Xu He brought a glass of water. Zhang Fangyuan wet the back of his hands and then put the toothbrush in the glass of water and soaked it lightly, then he poured some chinese honey locust tooth powder on the toothbrush, so that the tooth powder would stick to the bristles and made it easier to brush the teeth.

The few scholars looked at it seriously, no less than when they were hearing the master talked about the article they interested the most in in the academy. They saw Zhang Fangyuan gently rubbing the back of his hand with a toothbrush, and then rinsed the back of his hand clean. The dirty part was immediately restored to cleanliness, and there was still a scent of chinese honey locust left.

" If you use this to brush your teeth, it’s best to clean your teeth after dinner, clean your teeth at this time in order to avoid food residues left in your mouth overnight, which will damage your teeth in the long run. When you wake up in the morning, use it again before breakfast, your mouth will be fresh, your mouth will be fragrant, and you can have a good conversation with others for a day. "

The two scholars listened to Zhang Fangyuan's detailed explanation, and finally laughed out loud. When one of the scholars was excited, he ignored the coolness of the weather, habitually shook his folding fan, and praised directly: "It's wonderful!

"In the ordinary day, this student uses broken poplar branches dipped in salt, which can still remove the peculiar smell in the mouth, but how can poplar branches compare with this good thing." The scholars like elegance and cleanliness the most, and now when encountering this good thing, it was unavoidable to have the feeling like they found a treasure: " May I ask how much the teeth brushing that the shopkeeper said is worth?"

"It's divided by the hair quality. Ordinary pig hair is fifty copper coins if it’s not carved, and horse hair, both soft or hard is eighty copper coins. If you want the one carved with flower, add ten copper coins."

Xu He listened to Zhang Fangyuan's full-fledged quotation, and slightly thinking that this price couldn’t be called affordable.

The two scholars compared them, and they were more inclined to the carved ones. Although the uncarved ones were also novel, but who could refuse to have a toothbrush with more beautiful flowers. Zhang Fangyuan went on to shoot the fire again: "This toothbrush can be used for two months, and it’s a private thing, so it can only be used by yourself. Why don't you gentlemen be more generous to yourself, shouldn’t it be better to choose the carved one? It’s elegant, and it can better set off the charm of the gentlemen."

Pierced thousands, pierced ten thousand, but flatterings couldn’t be pierced.

[千穿万穿马屁不穿 it means flattering: to flatter and please people with sweet words. Everything can be seen through and hated, only flattering will not be hated. Everyone loves to hear flattery.]

"Then I'll take a toothbrush with carved plums." But the scholar was puzzled again: "But what's the difference in the quality of this hair?"

"Horse hair is very valuable. If the teeth are often red and swollen and easy to ooze blood, then choose horse’s mane hair. If the teeth are healthy and want to remove the dirt as much as possible, then choose horse’s tail hair. Pig hair is in between, but it’s still not as good as horse hair. It depends on which one you need. "

The scholar suddenly said: "The weather is hot in summer, and the mouth often smells of blood, so I will use the one with horse's mane hair."

"Haha, Brother Fu chooses plums, so I will choose orchids."

The four choices were plum, orchid, bamboo and chrysanthemum, and after that Zhang Fangyuan urged them to buy tooth powder.

The scholars were dazzled by the various of tooth powders, whitening, teeth-healthy, breath-cleaning, internal fire-reducing...the so-called art industry had specialization, and the effects of tooth powder specialization were also different.

A small shop could be said to be an eye-opener for the scholars.
