The preview of "The Charming Little Widow (Sixty)" is available next door. Please collect it. Mechanical engineer Zheng Limin transformed into a cannon fodder female supporting character in period novels. In the 1970s, machinery was backward and dependent on imports. Coinciding with the reform and opening up, there are many wastes waiting to be done. Touching the sugar-making equipment that was once displayed as an antique, Zheng Limin's eyes lit up. If you gain ten years of youth out of thin air, why not worry about serving the motherland? *** Unexpectedly, the first problem in traveling through time was not the harsh environment, but being forced to get married. Faced with a domestically violent man who wanted to marry Pu Xin and use her as a cash machine, Zheng Limin decisively chose Shen Lixuan, a veteran with an upright appearance. Shen Lixuan has strong features, a tiger's back and a wasp's waist. He is capable on the battlefield and in the kitchen. She is diligent and thrifty, fully supports her career, and keeps her home in order so that she has no worries. After marriage. The daughter-in-law of another family gets up early and goes to bed late, while the family is busy with snacks and drinks. Zheng Limin ate three meals a day prepared by her husband and devoted herself to renovating the bagging equipment in the food factory. Another daughter-in-law gave birth to a second child, and she was worried that it would be a girl again. With the loving support of her husband, Zheng Limin improved the sugar-making equipment, allowing sugar to enter every household and no longer become a luxury product. Many years later, China not only developed nanomolecular materials, but also had its own integrated circuit production line. The male and female protagonists of the original novel are still running around for three meals a day, and Zheng Limin is receiving national commendation on TV. Zheng Limin: The lifeline of national science and technology can only be in our own hands! Everyone learns from what he or she knows, so that the country can be strong and prosperous without being invaded by foreign forces, and can stand on its own on the earth. —— Zhan Tianyou Tip before viewing: Make assumptions and do not accept evidence. Just say you are right. Intention: Endless struggle
