As an AI language model, I am not able to determine exactly which flower you are referring to as "red Chinese flower." However, there are various flowers that are native to China and have a red color, such as:

1. Chinese Hibiscus (Hibiscus rosa-sinensis): Also known as China Rose, this plant is a popular ornamental flower in China with large showy flowers in shades of red.

2. Peony (Paeonia): Peonies are native to China and are highly prized for their large, fragrant blooms in shades of red, pink, and white.

4. Chinese Azalea (Rhododendron simsii): This plant has bright red or pink flowers that form clusters and bloom in the spring.

5. Chinese Rose (Rosa chinensis): Also known as Chinese tea rose, this flower has large, fragrant blooms in shades of red and pink.
