Reveal why Jiang Jingguo does not recognize Jiang Xiaoyan.

Small swallow is the biggest illegitimate child of Jiang Jingguo and Zhang Yaruo. 1942 was born in Guilin, and his twin brother's name is kitten. Unfortunately, their mother died unexpectedly when they were less than half a year old. Later, under the arrangement of Jiang Jingguo, the young Heavy Hair and Two Hair were taken from Guilin to Wan 'an, Jiangxi, and raised by their grandmother's family. Later, Zhang Haoruo, the eldest brother, became the county magistrate of Tongren County, Guizhou Province, and two brothers, Da Mao and Er Mao, were also taken with them, officially taking "Zhang" as their surname and entering the kindergarten. Usually, the two brothers are led by their big uncle, sitting on horseback and walking around the village. They were deeply impressed by the beautiful scenery and colorful folk culture in the southwest. 1945, after the victory of the Anti-Japanese War, Xiao Yan and Xiao Ci moved to Nanchang with their grandmothers, entered Hongdao Primary School, a missionary school at that time, and received formal western education. During this period, they also studied China's calligraphy and ancient poems with their grandfather Zhang, which laid a good foundation for their later interest in China's traditional culture.
