Mr. Ma Manchang studied calligraphy and painting with my father since childhood, and studied painting for decades. He was well versed in flower-and-bird calligraphy. He was taught by Zhang Shijian, Jiao Kequn, Wang Xilin, Ge Guilin and other famous teachers, and learned from Zhu Da, Ren Bohua, Wu Changshuo, Zhang Daqian, Li Kuchan and Wang Xuetao. His works are bold and unrestrained. They are well-known in the painting world because of their profound skills and talents. They are famous for painting chickens, eagles and peonies. The cocks painted in the works are pleasing to the eye and regarded as top grade. The goshawk painted is magnificent and has different shapes. The long scrolls "Hundred Chickens Picture" and "Heroes Meeting" are loved by people from all walks of life.
