The Second Mobile Detachment of the Beijing Armed Police Force has carried out the "three letters and one letter" activity in depth - the practice test promises to demonstrate loyalty "The harder you work, the better you will be." Recently, the Second Mobile Detachment of the Beijing Armed Police Force has extensively carried out the "three letters and one letter" activity with the theme of "a letter of goal to yourself, a letter of commitment to relatives, a letter of determination to the organization, and a letter of encouragement to veterans", Soldier Li Jiannan wrote a sentence in his "book of goals for himself", which expressed our common aspiration. For some time before, Li Jiannan was not motivated enough to work, and his training results were good and bad, and he was the target of company cadres. After the activity of "three letters and one letter" was launched, the cadre backbone of the squadron encouraged him to find the right goal and clarify the direction of his efforts. With the care and help of everyone, Li Jiannan's training performance has been significantly improved and his work and study are full of enthusiasm. Speaking of the experience of the event, Li Jiannan sighed with emotion: "The achievement of the event embodies everyone's hard work and sweat. I will continue to work hard to repay the trust of the organization and the care of my comrades in arms with practical actions." The leader of the detachment introduced that since the launch of the "three letters and one letter" activity, they have actively encouraged the officers and soldiers to set goals for themselves, make commitments to their relatives, express their determination to the organization, and mobilize the veterans to write letters to the officers and soldiers in active service for exchange, We will guide you to serve in peace of mind, strengthen your military skills and achieve good results. Many officers and soldiers have consciously changed and pressured themselves, changed "heteronomy" into "self-discipline", and changed "I want to do" into "I want to do". The ideological foundation of knowing responsibility and doing meritorious work at the post has become stronger. At the beginning of his enlistment, Private Xiao Chen felt uncomfortable with the strict management of the army. With the help of cadre backbone and comrades-in-arms around him, Xiao Chen has gradually integrated into the army family, and his training achievements have been steadily improved, and his style and discipline have been significantly strengthened. In the "three letters and one letter" activity, Xiao Chen not only set the goal in the "letter of commitment to relatives", but also sent the saved allowance to his parents on a monthly basis. "The education and training of the army has made Xiao Chen have a plan for life and a responsibility for his family. For him, this is a huge progress..." After receiving the letter of commitment from his son, Xiao Chen's father immediately called the army leader, and his words were full of gratitude and relief. Since the launch of the activity, there are still many officers and soldiers in the detachment who have changed their ideological outlook. During the event, Liu Yuhui, who was promoted by private soldiers ahead of time to be a police sergeant, read out his "letter of determination to the organization" at the military conference, expressing his firm determination to promote youth with a struggle attitude, to live up to the times, to live up to the age, to hone his skills in practice, and to realize value in his post. "We must conscientiously perform our duties and work hard, make contributions to our actual positions, and repay our organizational care with excellent achievements..." Private Han Qibing received a letter of encouragement from veteran Yang Shangqing. He recalled the care and help of the veteran in his life and work, touched his heart bit by bit, and inspired his fighting spirit with past events, which further strengthened his faith in serving at ease and his determination to fight. Practice tests commitment and performance shows loyalty. The leader of the detachment said that in the next step, they will continue to do a good job in the next article of deepening the expansion and transformation of achievements, integrate the "three letters and one letter" activities into the whole process of the comprehensive construction of the army and the completion of major tasks, and guide more officers and soldiers
