Siheyuan: a Warm Sign-In from the Second Son of the He Family

Mechanical engineer He Yuchen opened his eyes and became the biological brother of He Yuzhu (Silly Zhu) and the elder brother of He Yuzhu in "Love in the Courtyard". Facing the 1960s when supplies were scarce and the human relationships were complicated in the courtyard house, a simple "daily check-in system" became the starting point for him to settle down and live his life. Rice, flour, grain and oil, life skills, a little change... Although the income from signing in is not earth-shattering, it has become a spark for him to warm his family and change his neighborhood. He respected the deaf old lady as his own grandmother, and turned Xu Damao into a "bad friend" brother. With his vision beyond the times and his silent goodwill, he quietly turned the gears of the courtyard's destiny: * A crucial helping hand allowed Jia Dongxu to avoid death and keep the backbone of the Jia family. * Qin Huairu, the former "blood sucker", straightened up and regained his hardworking nature with the help of his "teaching people to fish". * The mean and selfish Jia Zhang, thanks to her son's survival and the encouragement of the deaf old lady, became the most enthusiastic helper when the He family brothers and sisters welcomed a new child. She clumsily but sincerely rushed around, serving brown sugar water, coaxing the baby, and using her actions to interpret her belated gratitude. * Yi Zhonghai let go of his obsession and became a real "parent"; Liu Haizhong and Yan Bugui also found their true nature in life in a warm atmosphere. He Yuchen himself also gained the mutual love with Lou Xiao'e, built a warm family, and even got a caring and lovely goddaughter - Sophora japonica. This is a story about ordinary heroes who use "check-ins" to accumulate small fortunes, protect family, friendship, and neighborliness in the torrent of the times, and finally let the entire courtyard bathe in the warm years.
