Yu or 于 - The Roots of Chinese Surnames: Exploring Heritage and History
The Yu (于) surname has two primary origins, both deeply rooted in ancient Chinese history, where its lineage intertwines with craftsmanship, nobility, and the rise and fall of dynasties.

The Yu Tribe of the Shang Dynasty
The first origin of the Yu surname traces back to the Yu Tribe of the Shang Dynasty (1600 BC — 1046 BC), a skilled group renowned for crafting exquisite round-mouthed containers.
Their advanced craftsmanship and dedication to perfection made them highly respected artisans of their time.

Recognizing their exceptional talent, King Wu Ding (? — 1192 BC) incorporated the Yu Tribe into his rule.
He granted his son the title of Marquis of Yu, entrusting him with governance over this land.
As time passed, the State of Yu flourished, growing into a formidable force.
However, when King Wu of Zhou (? — 1043 BC) waged war against the Shang Dynasty, the warriors of Yu fought fiercely yet ultimately fell in battle.
With the collapse of the Shang Dynasty, the people of Yu were displaced from their homeland.
To honor their ancestors, many adopted Yu as their surname, preserving their heritage through generations.

The Yu State under the Zhou Dynasty
After the fall of the first State of Yu, its land remained strategically significant.
Later, this territory was granted to King Wu of Zhou’s second son, who established another State of Yu under the feudal system of the Zhou Dynasty (1046 BC — 256 BC).
Yet, as the power of the Zhou kings waned, the small Yu State fell to stronger rivals.
Some of its descendants retained the rare surname Yu as a tribute to their lost homeland.
Others modified the character by removing the right-side radical, which symbolized a city, marking their departure from their ancestral land.
This alteration formed the more common and widely recognized surname Yu, regarded as the most orthodox origin of the name.

The Enduring Legacy of the Yu Surname
As time went on, the Yu family continued to flourish, producing many distinguished figures whose contributions left a lasting mark on history.
From governance and military strategy to cultural advancements and scholarship, Yu descendants played significant roles in shaping Chinese civilization.
From the skilled artisans of the Shang Dynasty to the noble rulers of the Zhou era, the Yu surname carries a legacy of resilience and honor.
Though dynasties have risen and fallen, the name Yu endures—flowing like an unbroken thread through time, carrying with it the echoes of an ancient past.
