The Phoenix and Peony pattern originated in 1950s China and was designed by the Design Department of Shanghai East China Textile Bureau. This design style features bold color combinations of red and green. At that time, Chinese fashion was dominated by black and other dark colors, so this innovative and vibrant design quickly swept across the country. This special edition in blue incorporates the latest development of BPCC's photochromic ink technology. The indoor card back has a white background, but when exposed to sunlight or UV flashlight, an elegant blue color will appear.
