Family Background
I come from a rural family in Huining County, Gansu Province, where my parents are farmers. As they age, their physical strength has declined, and caring for my 80-year-old grandfather adds to the family's responsibilities. Additionally, my brother is also a university student, making the annual tuition fees a significant financial burden for my family. Despite these economic challenges, I have never lost hope, firmly believing that hard work leads to success. To alleviate my parents' financial burden, ensure the continuity of my studies, and prepare myself to repay my parents and contribute to society in the future, I hereby formally submit my application for the National Encouragement Scholarship. I earnestly request the school and the department to review my application. In the future, I will demand even more of myself to achieve excellence!
Receiving this scholarship would not only be a great honor but also a significant validation of my academic achievements. It would motivate me to pursue my goals with even greater perseverance, passion, and determination throughout my studies and life.
Sincerely,
Respectfully,

家庭状况
我来自甘肃省会宁县的一个农村家庭，父母皆为农民。随着年龄增长，父母的身体状况大不如前，且家中还有一位八十岁高龄的祖父需要悉心照料。此外，哥哥目前也在读大学，我们两人的学费对家庭而言是一笔沉重的负担。尽管经济条件艰苦，但我从未放弃对知识的渴望，始终坚信通过努力定能收获回报。为了减轻父母的经济压力，确保学业顺利完成，并为了将来能更好地回报父母、感恩社会，我郑重向学校提交国家励志奖学金申请，恳请学院领导审核。在未来的学习生活中，我定将更加严于律己，争取取得更优异的成绩！
若能获得学校和学院的批准，这不仅是对我过往成绩的肯定与鼓励，更是一份沉甸甸的荣誉，将激励我在未来的学习与生活中，始终保持执着、激情与奋斗的力量。
此致
敬礼
