I actively participated in the daily work affairs, understood the importance of civil affairs to the people's livelihood, and contributed my own strength to serving the masses. - When I was working at the Financial Media Center, I participated in the filming and editing process of television news and new media news. Through this process, I saw the attitude of the grassroots officials to serve the people and strengthened my career ideals. - In the activities organized by the county committee, I learned the skills of communicating with people, such as speaking softly to avoid misunderstandings.
