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 haplogroups B4 and B5 are quite frequent in both northern and southern Han Chinese populations. 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, centered in Zhongyuan, China's Central Plain. The spread of Han people, language and culture from northern to southern China only occurred in the last 2,000 years, and was likely driven by warfare and famine in the north.
