Yes.
The Hakka ethnic group is dominated by Han people. The main cultural characteristics and manifestations of its culture are that it inherits the culture of the Han nationality in the Central Plains, so it should be definitely a branch of the Han nationality. However, this ethnic lineage is not of pure Han origin, nor is its culture pure Central Plains Han culture. Therefore, as a group, its members should include members of different ethnic groups that integrate with each other and share the same cultural characteristics.
Therefore, "Hakka" is the name of a Han ethnic group, but it is not a racial concept, but a cultural concept. "Hakka" is the name of one of the Han ethnic groups. This ethnic group called "Hakka" was formed by the Han people who moved south and gathered in the areas connecting Fujian, Guangdong and Jiangxi from the late Tang Dynasty to the middle of the Ming Dynasty, and merged with the local Sheyao and other indigenous residents.
A Han nationality with a unique dialect, culture and characteristics that are different from other Han nationalities. It is dominated by the Han people, and also includes She Yao and other ethnic minorities who have been "objectified" through the integration of scriptures.

Historically, almost all ethnic groups have experienced migration through the dynasties and developed to this day. The aborigines in Beijing, Shanghai and other places today are based on several ethnic groups. Immigrants from a hundred years ago are the main body, especially the major ethnic groups in Guangdong, Fujian, and Taiwan. Therefore, during the thousands of years of migration history, the Hakka people have become aborigines in many places like other migratory ethnic groups.
The origin of the Hakka began during the Qin Dynasty when Lingnan merged with Baiyue. It developed through the Wei, Jin, Southern and Northern Dynasties, Tang, and Song Dynasties. At the latest, it formed a relatively stable ethnic group - the Hakka in the Southern Song Dynasty.
There are approximately 80 million Hakka people in the world. About 50 million of them are distributed in more than 180 cities and counties in 19 provinces in southern China. The number of local Hakkas in Guangdong Province has reached about 25 million, accounting for one-third of the local ethnic groups in Guangdong.
About 6 million people are distributed in Hong Kong, Macau, and Taiwan, and about 15 million people are distributed in more than 80 countries and regions including Indonesia, Malaysia, Thailand, Singapore, Vietnam, the United States, Peru, and Mauritius. Hakka Slang is also an important part of the local language.
