Jiang Weiguo is Jiang Defu's first child and the apple of his eye. He was forced to go to the countryside during the Cultural Revolution, which had an important impact on his later life and career development. Jiang Weiguo's IQ is higher than that of Jiang Weidong, but lower than that of Jiang Changyi. His kind personality also made him have the best ending among Angie and Jiang Defu's five daughters.
Jiang Weidong is the second child of Jiang Defu and Angie. Compared with Jiang Weiguo, his personality is plain, but his fate is contrary to that of Jiang Weiguo. However, Jiang Weidong finally succeeded, relying on the big tree Jiang Defu.
