Mr. Hyun Pu finished washing in the morning and sat leisurely in the house and drank tea.

Fuso was at this time when matcha and green tea coexisted.

Fuso tea species and tea culture come from China, the earliest recorded record of tea drinking appeared in the early Nara period (710-794), the oldest tea garden in Fuso is in Kyoto Kozanji Temple, built by the most Cheng monk who returned from China in 805, and the first tea book "Eating Tea and Nourishing the Body" was written by the monk Rongxi who returned to Fuso from China in 1191.

The originator of the Japanese tea ceremony was Murata Zhuguang (1423-1502), who joined Zen with Ichi Sojun (the famous monk Ikkyu) and introduced Zen Buddhism into tea culture and founded the tea ceremony.

In 1489, Ashikaga Yoshimasa, the eighth shogun of the Muromachi shogunate, lived in seclusion in Higashiyama, Kyoto, where he built Ginkakuji Temple and the famous Tongrensai. The floor of Tongrenzhai was covered with tatami sheets, and a total of four and a half tatami sheets were used, and since then, the area of four and a half tatami has become the standard of the Fuso tea room.

At the end of the 16th century, Sen no Rikyu (Senshoyi) of the Momoyama period formally established the tea ceremony, and the four noble truths of the tea ceremony, "harmony, respect, purity, and silence", became the essence of tea ceremony culture in the future.

The famous "one period and one meeting" in the tea ceremony is to make the guests and hosts feel "once in a lifetime, rare once in a lifetime and should be cherished" through a series of tea ceremony activities, including water, rice, talk, and tea, which is quiet and slightly lonely, and then thinks about the joys and sorrows of life, so that the spirit is baptized and sublimated.

At this time, matcha is used in the tea ceremony, similar to the Chinese group tea, which is made by grinding it in a cage and brewing it with spices, and when drinking, it is necessary to draw a circle with a tea whisk (round bamboo brush) to evenly dissolve the tea powder. Green tea and black tea, which were also used in tea ceremonies in later generations, were no longer confined to matcha.

Fuso green tea originated around 1738, when Uji tea farmer Muneen Nagatani (1681-1777) created "sencha", or high-grade leaf tea, in which "young shoots are hand-picked with one bud and three leaves, thinly spread out to steam, kneaded on fire, and then dried in a roasting oven."

At the beginning of the 19th century, the improved method of making tea by Nagatani Soen was widely popularized and popularized in Fuso. In 1837, Tokuon Yamamoto created the best sencha tea, "Gyokuro tea", and since then, green tea has been widely recognized and has begun to spread widely among the people.

Naohide came back with two students from exercising, and two of Mr. Genpo's disciples also came out to take their seats - they used to sit on the wooden floor and could only be regarded as sitting, but now it is different, yesterday Naohide in the merchant town ordered a tatami mat and a round cushion (round cushion), and asked the merchant to deliver it to the door and lay a stack on the house. Now that everyone is sitting on the throne, the sense of happiness has risen in vain - sitting on the cool floor with bare thighs, it is really a shame for Mr. Xuan Pu to think of it. Naoxiu has always believed that no matter how busy he is, he can't deal with it, and when the living conditions are good, he will be happy, and his work efficiency will increase.

The servant brought rice, miso soup, sweet vinegar ginger sprouts, and served a tea bowl of steamed egg custard (a deluxe version of egg custard) to Mr. Genpo, Toranosuke, and Gakujiro, and Mr. Genpo's two students and Naohide each had only one "egg burning" (boiled egg).

Naohide brought some sencha and flavored pickles from Nagasaki when he came to Saga, and bought some local pickles and miso for the past two days. Mr. Xuan Pu belongs to the kind of person who is busy cooking pocket watches, although he is a doctor, but his life is really sloppy, it is estimated that Mr. Xuan Pu's two students and servants are embarrassed to remind him, in the atmosphere of East Asian culture, sometimes people live cautiously, sometimes they just think too much, they can do it and they can't do it, and it is good to go with the flow, thinking too much will only embarrass themselves.

After eating and arriving at Lan Xueliao, Mr. Xuan Pu went to be busy, Naoxiu was excluded from the iron pen engraving because of the font, he flipped through the collection of Lan Xueliao, the quality was average, the majority of Lan medical books, only one professional physics book translated by Shizhu Tadao "New Book of Calendars", only one professional chemistry book translated by Udagawa Rongan "Shemi Kaizong", as well as a book on metallurgy and casting "The Complete Book of Iron and Mercury" and several natural encyclopedias compiled by Lan Guo. It seems that Lan scholars are more passive to accept Western science, and the librarians of the Lan State Commercial Museum also spread knowledge according to their own preferences and specialties, and the books lack systematization.

As for the famous "Artillery Casting Method of the Royal Liege Foundry", Naohide didn't find it, and it is estimated that Saga had not yet gotten this book from the Lankoku Merchant House, and it was this book that led the Saga clan to start building a reverberatory furnace, and then to create a Western-style steel cannon.

Turning around, Zhixiu always felt that compared to the universities of later generations, Lan Xueliao was missing something, think about it carefully, it turned out that these things were missing, Zhixiu said hello to Mr. Xuanpu and asked for leave to go out, Mr. was busy carving and only waved his hand gently, so Zhixiu took the two students to slip away.

In the blink of an eye, Naoxiu has been in Lan Xueliao for the fifth day, and several gentlemen have mastered the skills of wax paper printing, and the wax paper printing equipment has also been expanded and purchased into eight sets. On the afternoon of the fifth day, the rough version of "Optics" was finally printed, a total of eight copies, and several gentlemen and Lan scholars who had temporarily come from the Hongdao Hall to help congratulate each other, and Naohide and the students also made joy on the side as a background board.

After the celebration, Mr. Xuan Pu and Mr. Lan Xueliao rushed out of the door with books and wax paper printing equipment, leaving Naoxiu and others to look at each other, "What's the situation?" I shouldn't have given out some bonuses to have a dinner or something, and that's it......."

When I didn't see a few gentlemen come back at dusk, Nao-su took the student and Mr. Xuanpu's two disciples home for dinner. Mr. Xuanpu's disciples have long discovered Zhixiu's local tyrant attributes, but in fact, Zhixiu has been a little drifting recently before spending money lavishly, one reason is that the poor family has a lot of budget for rich roads; The other is that Naoxiu is a little stressed in the face of an unfamiliar environment and historical celebrities, so he spends money like water to relieve it, and his two students have a little admiration for him and don't remind him.

It's not a big deal in the past three days.,When I went out, I saw the details of the lives of civilians in the merchant town.,It's slowly calmed down.,But there's a lot of good and cheap food.,The key is to be able to do it.,So everyone still has a lot of expectations for dinner.。

It's early winter, and the seasonal vegetables are gone, and the only green ones are kelp (similar to kelp), but Naohide bought some soybeans and came back to sprout bean sprouts, making a cold bean sprout crisp and refreshing. The same is true for potatoes, Naohide simply processed the iron sheet with nails and made it into a kitchen tool, and the cold shredded potatoes are also delicious. And how good it is to roast satsuma taro (sweet potato) on a tin sheet, and it is good to eat delicious roasted sweet potatoes in winter.

There are also dried gourds and other dried vegetables, and it is better to put some of them in the soup than to make radish soup every day.

Tuna, mullet, sardines, spotted catfish, dried herring and dried herring roe are considered inferior foods and are very cheap, and in winter, tuna pieces and green onions are boiled and eaten hot, making the green onion tuna pot very tasty.

In addition, Naohide made a seasoning similar to thirteen incense with medicinal materials in Edo, and he brought a large bag with him on this study tour, which is an artifact now, and whoever eats it knows.

It seems that the cost is not small, but in fact, the quality of life has been greatly improved, in the past, Mr. Xuanpu lived more casually, what to eat, and the servants were not good at innovation, and the servants learned after a few direct instructions, and the motivation to learn was very sufficient, because the master ate what he ate, and no one would get along with himself.

In the evening, Nao-su and a few people were chatting, and Mr. Hyun Pu came back, and after drinking a cup of tea, he asked Nao-su to prepare, because Nao-su was going to give a lecture to the students of Hongdaokan in the medical hall tomorrow.

"Sir, what are the aspects of the lecture?"

"The content is your own choice", Mr. Xuan Pu is a kind person, but as one of the three famous doctors at the end of the shogunate, "the sea is a thousand mountains and a thousand" (well-informed, proficient in the world), I have also eaten and seen, and I am very open-minded, and I will not care about this and that, and I have the confidence of "what a moth old man has never seen".

The next day, Zhixiu first went to Lan Xueliao to move the things he had made in the past few days to the classroom of the medical hall, saying that it was a classroom, but it was actually the hall of a house, which seemed to be able to accommodate thirty or forty people.

It turned out that yesterday Lan Xueliao and everyone ran to show off their printed "Optics" to the owner of the medical hall, Shimamoto Liangshun, and Shimamoto Liangshun took everyone to the Hongdao Museum to show off, and the results must be known to the leaders at the first time.

Praise must be praised, and rewards must be rewarded, but Mr. Xuan Pu said that the inventor is going to leave in the past two days, as a samurai of the Naoxiu shogunate, don't laugh, the second half is also a hereditary samurai, and the reward is not very easy to do, and there is a suspicion of collusion in private to send money, and cultural people are also cheesy when they talk about money, so if you think about it, then give him a name, and the thing is done above board and it is still a beautiful talk, so there is this lecture.

In the Edo period, the time was told by taiko drums or bells, and there was no accurate concept of time, so one after another Kodokan students entered the hall and gathered in small groups to whisper. Naoxiu maintained his manners, his back and legs ached, and he finally saw that there were more than 20 people, so he asked Xuejiro to invite Mr. Xuan Pu and a few Mr. Lan Xueliao to press the scene and start lecturing.

The students who came from the Hongdao Hall were mainly from 15 to 17 years old, and the Lan Xueliao was the place where the Lan Xue was studied, and the Hongdao Hall was the place where the students were formally taught. The notice of the Hongdokan is that "Edo so-and-so, Yu Lanxue has a reputation, and the next morning he will give a lecture at the medical hall so-and-so Yashiki, and those who are interested can go by themselves", Naohide is not famous, and he is still a young person when he inquires, so the people who come to listen to the lecture are all young students, and they are basically all having a good time.

Naohide knew in his heart, "Walk by, don't miss it, there will be times when you regret not coming", smiled (smirked) and walked to the blackboard, picked up chalk and wrote two columns of big characters, "Edobori Naohide", "Orchid Scholar".
