Find a sample research report online and write it against each other.

Since the two are to be arranged, of course one is in front and one is last, if so"Du Li"then you might ask why not"Li Du"This? It's just a sequence. However, Li Bai is indeed earlier than Du Fu, which may also be a part.

At that time, Li Bai's status and fame in society were higher than Du Fu's, so Li Li first and then Du.

Li Bai was a poet in the middle and early Tang Dynasty, and Du Fu was a poet in the middle and late Tang Dynasty, because of the chronological order.

The Tang Dynasty also had little Li Du's: Li Shangyin and Du Mu.

There may be two reasons, one is that Li Bai's fame was greater than Du Fu at that time, and the other is that he is older.

But I don't think this in itself has any meaning, maybe that's what it's called, why bother thinking so complicated.

It should be ranked by age, not to mention that it is easier to pronounce.

You can read more of the two readings, one is smooth and the other is not.

Get used to it, why are mountains and rivers not mountains of water, why are heaven and earth not earth and heaven?

Li Bai is older than Du Fu and became famous earlier.

There are many versions of the surname Li in history, and the earliest version can be traced back to the surname Ying.

The blood ancestor of the surname Ying is the leader of the Dongyi tribe Gaotao, Gaotao was appointed as the ** in charge of law enforcement or criminal law during the period of the Emperor Instant, which was called Dali at that time, and the word "Li" was the same as Li in ancient times, so it got the surname.

Of course, in addition to this version, there are several theories:

1. Plum tree totem

Legend has it that the ancestors of the Li clan were distressed by the lack of food during the suffering, when there was a tree next to them that produced fruit, and the ancestors used the fruit of this tree to impact, thus saving their lives, and the entire Li clan was also continued, so the Li clan was grateful for this tree, and respected this tree as the totem of the Li family, so many people surnamed Li usually planted a plum tree in the yard of their homes if they were able to plant trees.

2. Originated from the country of Bazi

Legend has it that after King Wu of Zhou exterminated the Shang Dynasty, the people in the Banan area of Chongqing at that time were called Ba Ziguo, in 306 AD, the Ba people established the Dacheng State in the Sichuan region, and the history called this country Chenghan, this country is the first kingdom established by the Li family, and it is also the first dynasty established in ancient China.

3. Derived from reward

During the Three Kingdoms period, after Zhuge Liangping of the Shu Han Dynasty, he was a local ethnic minority, and these surnames included Zhang, Zhao, Li, Yang, etc., and the surname Li also received a certain inheritance from this time.

As one of the four major surnames of the Chinese nation, people with the surname Li are very widely distributedAnd now there is no exact statement about the source of the Li family, usually some ancient legends or legends, and even do not have a certain historical reference, but some legends are very likely to have similar things at that time to form, so these legends can also have reference value to a certain extent, or these legends are more or less true, but the original source, now there is no information to verify.

1, the source of the surname Ying.

It is believed that the Li family originated from the surname Ying, and the blood ancestor was the leader of the Dongyi clan, Gao Tao (a blame, Yan surname or win surname), Gao Tao was appointed as Shun's Dali (the official in charge of criminal law), so the official family was Li ("Li" and "Li" ancient words are connected), first for Li, and then for Li. The ancestor of the surname is Li Li, and Li Er is the eleventh.

2, Li Shu totem said.

Li got the surname Li because of the official of Dali, and later the surname Li because he took refuge in Muzi for food. Because the plum it eats is a wild plum, it is cultivated by the Lee family to become a domestic plum tree, and the plum tree is a sacred tree, that is, a totem tree. Therefore, the descendants of the Li family often plant plums next to the house as a symbol, and this habit is still preserved.

There is a peach and plum orchard in Li Bai's house, and plum trees are planted in the imperial palace garden of the Tang Dynasty.

3, the source of Ji's surname.

During the Shang Dynasty, there were descendants of the same surname of Zhou, named Ba people, who lived in Zhongli Mountain (now northwest of Changyang, Hubei). After King Wu of Zhou destroyed the Shang Dynasty, the Fengba people called Ba Ziguo in Yuba (now Banan District of Chongqing). In 306 AD, the Ba people established the Dacheng State in Sichuan, known as the Cheng Han Dynasty, which was the first dynasty established by the surname Li in China.

4. Originated from the reward of the surname and the restoration of the Li family.

During the Shu Han Dynasty, after Zhuge Liangping mourned and razed, he gave the local ethnic minorities Zhao, Zhang, Yang, Li and other surnames; During the Northern Wei Dynasty, after Xiaowen moved the capital to Luoyang, the policy of comprehensive sinicization of culture was implemented, and the Xianbei people had the surname Li and was named Li. The Xianbei Tuoba clan of the Northern Wei royal family is actually a descendant of the Han general Li Ling.

1. From the surname Ying, he is a descendant of Emperor Gaoyang. When Yao, Gaotao once held the position of Dali (the official in charge of the prison), and his son Boyi was given the surname Ying, and the descendants of the descendants inherited the position of Dali for three generations. There are two ways to say that Lee changed to Lee.

One theory is: during the Shang Dynasty, the descendants of Gaotao Li Zheng, as an official in the court, because of the direct advice offended the king of Shang, and was executed, his wife Qi and the family fled with his son Lizhen, because of eating plums to satisfy hunger, so he did not dare to be reasonable, so he changed his surname to Li. Another way to put it is:

According to the record of "Surname Strategy", there was no Li family before Zhou, since there was Lao Tzu's surname Li, Ming'er, a descendant of Li Zhen, because the ancestors were officials for the previous generation, and the words Li and Li were intertwined, so they also took Li as their name. Obviously, the Li family began with Li Er's surname.

2. Change the surname from another ethnic group. During the Three Kingdoms, Zhuge Liangping mourned and gave the local ethnic minorities Zhao, Zhang, Yang, Li and other surnames. Xianbei has a compound surname Li, and after sinicization, it was changed to a single surname in Chinese characters. It is for the Luoyang Li family.

3, from his surname changed to Li. According to relevant information, the founding fathers of the Tang Dynasty had 16 clans, including Xu (Xu, An, Du, Guo, Ma, Xianyu, etc., who were given the surname Li from the Tang State for their meritorious service.

Li first referred to Lao Tzu's surname, which was the first well-known celebrity in the Li family, and later Li Guang and Li Tang began to be widely known.

The blood ancestor Gaotao was appointed as Shun's Dali, and then the official family was the Li clan, first the Li clan, and then the Li clan. The surname Li originated from totem worship, with the plum tree as the totem.

The surname Li is widely distributed in China, mostly in the north, and almost all over the world overseas. According to ancient data, the surname Li is the surname of 嬴 (ying) 颛 (zhuan) 顼 (xu). Before the Tang Dynasty, the surname Li was mainly developed in the north, and only distributed in some areas south of the Yangtze River.

The ** surname Li originated from the ancestor of the Tang Dynasty, Li Shimin, who was the emperor of the Tang Dynasty, when Li Shimin ruled the Tang Dynasty for decades, and the Li family was able to carry forward and inherit to this day.

It should be Li Bing's father and son!!
