Ma Yumei's fields are calligraphy and painting.

In the field of calligraphy and painting, Ma Yumei has considerable attainments. She is proficient in brush calligraphy and is good at writing official script with brush, which is vigorous and powerful. After liberation, it often came in handy in the slogans of wall newspapers. The pen is particularly long, cursive, full of twists and turns, and it penetrates the back of the paper. That's called a talented woman with both hands. Art works are good at peony, lotus, lotus, plum blossom and other flowers and plants, especially exquisite embroidery skills. In his early years, he held many personal embroidery and painting exhibitions, and his works have great prospects in the field of collection.

During the war of blood and fire, Ma Yumei's brother Ma Zhong (Zhao) and he successively devoted themselves to the revolutionary cause and made immortal contributions to the establishment and consolidation of the Jin-Sui revolutionary base area. On the eve of the Japanese surrender, the Central Jinsui Branch appointed the eldest brother Zhao to go deep into Yanmen and Suimeng areas on behalf of the Jinsui Branch, under the alias of Ma, Ma Ge, Ma Jun and Mark, to be responsible for guiding the urban work and cooperating with the main forces to receive Suiyuan and liberate Datong. Ma Yumei contacted his brother in many ways, trying to send a message for the early liberation of Datong. During the War of Liberation, Ma Yumei went to the liberated areas many times under the escort of the responsible comrades of Datong Underground Party, such as Bai Qi, Xu Jianbao, Ma Qiyu and He Sanlian. Due to the tight blockade of the enemy at the gate, he never got what he wanted.

1In the twelfth month of 947, the Kuomintang authorities in Datong used the "three autobiographies" to slaughter producers and progressive intellectuals. At the beginning of the following year, the enemy spy got wind that the eldest brothers, Zhao Hebai Qi (Liu Shifu and Liu Yuezong), were the main leaders of the Jin-Sui underground party who participated in the liberation of Datong, and found out that their relatives still lived in Datong, so at midnight on February 9, 948 (New Year's Eve), they angrily ordered their special police minions to arrest Zhao's sister and Bai Qi's wife and sister Mi Fang (martyr). At that time, the enemy used cruel means such as tiger stools and pepper water to intimidate and torture and asked them to provide information about their loved ones. However, the two women would rather die than surrender to the ruthless enemy, leaving the enemy with nothing. On the eve of the liberation of Datong, the People's Liberation Army approached the big cities, and the enemy spy became more rigorous, persecuting revolutionaries crazily. During the hard years, Mr Ma Yumei was tortured during the day and was forced to copy materials, carve wax plates and print documents by the special police team at night. Keenly and bravely, she seized the opportunity of copying printed materials and took advantage of the panic of enemy agents to obtain a large number of valuable confidential materials and documents (including the "Four Corners Plan", the list of enemy agents and their families, etc.) from Datong Special Police Team. ) and entrusted Comrade Mi Fang who was released on bail pending trial in advance. At the beginning of the liberation of Datong (1May 2, 949), Mr. Ma Yumei once again took the important enemy spy materials stolen by Mi Fang and personally handed them to Kang Shi 'an, director of Datong Public Security Bureau, Liu Zhong, director of the urban area (Datong Public Security Bureau had the original procedures for handing over the materials), and Comrade Su Xing and Comrade Bai Qi from Shanxi and Suiyuan, providing first-hand information for the relevant departments to eliminate rape. 1954, after the Inner Mongolia public security organs captured Lu Ke, the captain of the Kuomintang special police team, they sent people to Datong to thank Ma Yumei and Mi Fang for their revolutionary actions.
