The Chinese ancient ethnic princess dress, also known as the mu-rong or "flower girl" dress, is a traditional costume worn by women in China during the Han dynasty.

It is characterized by its intricate embroidery, delicate patterns, and flowing fabric.

The dress is often adorned with headwear such as a headdress or a veil, which adds to its elegance and beauty.

The mu-rong dress was popular among the royal family and other high-ranking officials during the Han dynasty.

It was considered a symbol of wealth and status, and was often worn for special occasions such as weddings or festivals.

The dress was also used as a form of communication between different regions of China, as it allowed people from different areas to identify each other and establish connections.

Today, the mu-rong dress remains an important part of Chinese culture and is still worn by some people for special occasions or cultural events.

It is also a popular item in fashion and has been adapted into various styles and designs over time.
