?Looking for the roots. There are three sources of the surname Lan: 1. It comes from the surname Ji, after King Wen of Zhou Dynasty.

According to "Tongzhi Clan Brief", in the Spring and Autumn Period, Duke Mu of the Zheng State was named Lan, and his concubines were named after the king's father.

2. In the Spring and Autumn Period, there were officials in Chu who collected food from Yulan (the old city was fifty miles east of Zaozhuang, Shandong Province today), and later took Yi as their surname.

3. Coming from another clan or changing the surname from another clan.

The Wuluolan clan of Northern Xianbei was changed to Lan during Emperor Xiaowen's Hanization reform; the Mongolian surname of the Yuan Dynasty was Kara, and their ancestral name was Arslan, so their descendants took Lan as their surname; the Lanchak clan of the Yugu clan had a Han surname.

It was passed down to 627 BC, when Duke Mu of Zheng came to the throne.

Legend has it that when Duke Mu was born, his mother dreamed that an angel was holding a plant of orchid and gave it to her with great respect. The fragrance was fragrant, and when she woke up, she seemed to have an endless aftertaste. Soon after, she gave birth to a son, who she named Lan.

Ji Lan reigned for twenty-two years. After his death, he was given the posthumous title Mu and was known as Duke Mu of Zheng in history.

From then on to the Qin and Han dynasties, the Lan surname basically flourished and developed in the Central Plains.

During the Han Dynasty, the only Lan Guang and Mrs. Lan whose surnames were recorded in historical records were Wuling Prefect, Lan Guang, and Mrs. Lan, and there were only a few words about them, making it difficult to know the details.

During the Wei, Jin and Southern and Northern Dynasties, there was General Lan Shu in the Pre-Qin Dynasty, Lan Ziyun in the Southern Dynasty, Lan Qin and Lan Xia Li, father and son from Zhongchang Wei (now a famous name in Hebei Province).

It is widely distributed in today's Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan, Hubei, Fujian and other places.

At the end of the Yuan Dynasty, Shanxi was located in a special geographical location with mountains and rivers both inside and outside.

For the people in the Central Plains and Jiangdong areas who were suffering from war at that time, it was simply a paradise on earth, a paradise, so the surname Lan in Shanxi flourished.
