1.您集邮的起因是什么?谁是您最钦佩的集邮家?受家父李振华影响,我从上小学二年级开始集邮。父亲长期爱好集邮,生前担任陕西省集邮协会副会长、顾问,他的解放区票邮集曾获世界邮展银奖。父亲不仅帮我收集邮品、传授邮识,还鼓励我在集邮研究上下功夫。 1. What is the cause of your philately? Who is your most admired philatelist? Affected by his father, Li Zhenhua, I started from the second grade in elementary school. His father has long loved hobby, former vice president and consultant of Shaanxi Provincial Philatelic Association, and his Liberation Area stamp collection has won the Silver Medal of World Exhibition. My father not only helped me collect the philatelic products, but also encouraged me to study philately.
