Is lanling wine really produced in Changzhou?

I don't mean to throw cold water on it, but I also hope that the conclusion that lanling wine originated in Changzhou can be established. I am proud of my hometown. It's amazing that such a good wine can bother poetry immortals to sing exclusively. However, since it is a topic of folk culture, we should also adhere to the research principles of well-documented and rule-based. Every major conclusion should be supported by detailed cultural and historical evidence, instead of making inferences of "yes" and "completely possible" based on a loose chain of evidence, so as to avoid making international jokes and making people laugh that Changzhou has no culture. It can be seen that in the history of Changzhou, there was a short time called "Lanling". When he was called Lanling, Li Bai was at least in grandpa's thigh. When was Li Bai's masterpiece The Traveler of China written? Authoritative opinions were written in the Kaiyuan period, which was the heyday of the Tang Dynasty, before Li Bai went to Chang 'an. The place where he writes poetry is at the east foot. At that time, Li Bai lived on East Road. After returning from Chang 'an, I officially moved here in Tianbao. The so-called Donglu is the southeast of Shandong Province, which naturally includes Cangshan County of Shandong Province and borders Xuzhou, Jiangsu Province. There is a Lanling town in this county, which has produced lanling wine since ancient times. From the perspective of historical organization and evolution, Lanling County was established in the Qin Dynasty, and it belongs to Donghai County within the scope of Lanling Town. In the Western Han Dynasty, it was Lanling County in Donghai County of Xuzhou. During the Yongjia Rebellion, a large number of officials and people of the Jin Dynasty fled to the south. Huaiyin Ling led the Xiao clan in Lanling to cross the river to Changzhou, and set up Lanling County in Wujin, which was called "Nanlanling" in history. Then, this is basically consistent with the statement in Sui Shu. Changzhou was set as Lanling County in Liang Dynasty, which was a "temporary" setting. Therefore, after the Sui Dynasty unified the whole country, this organizational system was quickly abolished and the old organizational system in Changzhou was restored, which is in line with the basic laws of historical objectivity. About Cangshan lanling wine. China made wine very early, which can be traced back to Shang Dynasty. The cultural center of Shang Dynasty is located in the Central Plains of the Yellow River Basin, mainly in Henan, Shandong and northern Anhui. Until now, this area is still famous for its wine making, which can be said to be the birthplace of Chinese wine culture. Historically, Lanling was famous for its wine. According to archaeological data, 1995, two well-sealed altars of lanling wine were unearthed from Hanwang Tomb in Shizishan, Xuzhou, and the clay seal was engraved with the seal of "Lanling Seal". This is the direct evidence provided by archaeology. At this time of the Han Dynasty, Lanling was in the south of Shandong, but it had not moved to Nanlanling in Changzhou. At least, it shows that Shandong Lanling is the beginning of "lanling wine". According to relevant data, lanling wine was quite famous in the Eastern Zhou Dynasty. It is said that it was brewed by Xiao family in Han Dynasty, so it was also called "Xiao Wang wine". Since Xiao's clansmen traveled to the south, it is also possible to bring wine-making technology to Changzhou, so the relationship between Changzhou and lanling wine is limited at best. However, since the "Yongjia Rebellion", the war has never stopped in history. Even if the Sui Dynasty restored temporary calm, this area south of the Yangtze River was still ruled by Du, a peasant insurgent at the end of Sui Dynasty. I think it's a problem that ordinary people don't have enough to eat. Where can I make wine with surplus grain? Even if the rich brew a little by chance, it will not be the grade of fine wine. At most, it is a kind of rice wine that we are still brewing in the rural areas of Jiangnan today. This wine has neither the taste of "tulip" nor the color of "amber light", but a turbid and strong sour soup. Has Li Bai been to Changzhou? At present, there is no conclusion in Changzhou literature and history circles because there is no strong evidence. But they say that Li Bai has been to Liyang several times, which is evidenced by records and relics. Because Liyang belongs to Changzhou now, Li Bai has been to Changzhou. First of all, Liyang, where Li Bai lived in the middle of the Tang Dynasty, was not under the jurisdiction of Changzhou, but under the jurisdiction of Yixing County (now Yixing). Later, Xuanzhou and Jiangning were under their jurisdiction, especially during Xuanzhou. Therefore, Li Bai's visit to Liyang is tantamount to a visit to Changzhou, which is totally unreliable and ignorant of the local organizational system in history. Li Bai stayed in Liyang's famous Yuefu poem "The Roaring Tiger", which proved that he had been to Liyang, but an Anshi Rebellion was erupting at this time. Li Bai, who has been away from Chang 'an for several years, heard the bad news, and his feelings of grief and indignation were beyond words: "The Qin people were half imprisoned in Yan land, and the Hu horses turned over Luoyang grass", which is a true portrayal of the arrogance of the rebels in An Lushan. Li Bai's second visit to Chang 'an was in the first year of Tianbao, in the autumn of 742 AD. The "Anshi Rebellion" began in the fourteenth year of Tianbao, in 755 AD. At this time, Li Baizheng was busy doing one thing, that is, trying to contribute to the imperial court and participate in putting down the rebellion. So even if he passes by Liyang, it is impossible for him to raise his glass and sing lanling wine. Moreover, the name of this poem is "Visiting the Bank of China", which can be understood as him. However, both Li Bai and Du Fu were depressed during the eight years of the "An Shi Rebellion", and Li Bai was exiled and relegated on suspicion of participating in the Wang Yong Uprising. But even if it can be proved that Li Bai had been to Liyang before the Anshi Rebellion, Liyang has never heard of producing "Lanling fine wine" so far, and Li Bai must drink in Liyang. What brand of wine was produced at that time? This requires researchers to dig carefully. Li Bai, who is very familiar with the rules of the game in communication occasions, thinks that the wine is good at best, but he doesn't praise it with poems, because the host is not in Lanling, but in Liyang, Xuanzhou, eating other people's feasts but praising the specialties of other places with poems. This is obviously contrary to Chang Lun and does not conform to Li Bai's consistent style. We really can't find a convincing reason to prove that "lanling wine" praised by Li Bai is a Changzhou specialty. So now Changzhou people are trying to clear their names according to scattered historical materials and legends. Is it a kind of fantasy? I remember a long time ago, Changzhou produced a kind of white wine, which was the "Lanling" brand. This kind of liquor is very common, cheap and suitable for mass consumption. Please note that it is white, not the "amber light" described in the poem. "Amber light" is a metaphor, referring to the color of wine, which is the crystallization of sap flow of a thousand-year-old tree, light sauce color or light yellow. Lanling brand liquor is white and glass color. It is supposed that this wine-making technology will not be easily lost after more than a thousand years, and it should be documented, but Changzhou at that time did not become the "amber light" lanling wine. Now this kind of wine has disappeared in Changzhou. Why? Earlier, I heard that Lanling registered the trademark "Lanling" and was trapped in Changzhou because of "misappropriation". Changzhou people have no choice but to sell it. I want to ask someone who is talking about it in a high-profile way now. If you are really confident to prove that this "lanling wine" is a Changzhou patent, and history can speak, why don't you stand up and refute it like this?
