Zhu De wrote to Chen Zongyao, head of the 718th Regiment, Xiong Huang, acting political commissar, and transferred to Chen Waiou, head of the 717th Regiment, and Yan Fusheng, political commissar, praising the achievements made by the two regiments in the production movement and asking them to seize the opportunity to vigorously develop animal husbandry, transportation and handicrafts, and do a good job in commercial work.
