In the 1920s and 1930s, Hakka women in southern Jiangxi and western Fujian liked to wear Lin Lan best. When Mao Zedong led the Red Army of Chinese Workers and Peasants to open revolutionary base areas from Jinggangshan to Gannan, local Hakka women wore this blue cloth and took an active part in the revolution.

They cut off their long hair, tied armbands and marked their take-off shuttles, and joined the women's rescue team, the Red Guards, the Red Development Team, the stretcher team, the rescue team, the spring ploughing team and the front line team. In the fields, inside and outside the hospital, before and after the battlefield, you can see their blue figures from time to time.

Their military shoes protect the soldiers' feet; The uniforms they sewn warmed the soldiers' bodies; The rice they transported met the needs of soldiers; The ammunition they transported ensured the victory of the battle; Their melodious singing greatly inspired the fighting spirit of the soldiers; They honor their in-laws and raise their children, which is a solid backing for soldiers.

They cultivated the land and maintained a virtuous circle of production in the Soviet area with their own hands; Their youthful and beautiful blue figures, like silver needles, sew the front and back together tightly, blending the central Soviet area in southern Jiangxi and western Fujian, and shining because of their existence.

He Zizhen, Kang Keqing, Li Jianzhen, Wei Xiuying, Li Meiqun, Li Guirong, Mao Zejian ... These pearl-like names are the huge flowers in that blue ocean.
