Your paternal lineage may be linked to the Han Chinese
Haplogroup O-Page23 has been found in several populations of the Han Chinese ethnic group. The ancestors of the Han, called the Huaxia, lived in the upriver basin of the Yellow River 5,000-6,000 years ago. As agricultural technology improved, the Huaxia spread east and south, and became the Han Chinese. Over the last 2,000 years, there have been three major migrations of the Han southward. The first of these migrations occurred during the Jin Dynasty from 317 to 420 CE, when nearly one million people moved south. A second migration occurred during the Tang Dynasty, after the An-Shi Rebellion, between 755 and 762 CE. The last migration occurred during the Southern Song Dynasty, from 1127 to 1297 CE, when nearly 5 million people migrated southward. The Pinghua, a branch of Han in which haplogroup O2a2b1a1 is particularly common, may be descendants of indigenous minority groups that adopted Han culture during one such major migration event.
Your maternal lineage may be linked to the Han
Members of haplogroup D are found in both northern and southern Han Chinese populations at low to moderate frequencies. The Han people, who all share the same language and similar cultural practices, are the largest ethnic group in the world, with about 1.2 billion people. Historical evidence shows that Han people are descendants of the ancient Huaxia tribes that come from northern China, and Han language and culture only expanded into southern China in the last 2,000 years. The spread of Han people and culture from northern to southern China was likely driven by warfare and famine in the north.

What do people with the surname Yi have in common?
Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population. That said, people with the same surname are more likely to have similar ancestries than randomly sampled individuals. The reason is the tendency of people with similar cultural or geographical backgrounds to preferentially mate with one another. That's why people who share a surname may be more likely to share traits and tendencies in common than people within the general population.
