"集邮"在英文中叫做 "stamp collecting"。这个词源于英语中的 "stamp"，意思是邮票，和 "collect"，意思是收集。因此，"stamp collecting" 意思就是收集邮票。
例句：
"John has been stamp collecting for over 30 years." (约翰已经集邮30多年了。)
"I inherited my grandfather's stamp collection when he passed away." (我祖父去世后继承了他的邮票收藏。)
"I bought a rare stamp at the stamp collecting fair last weekend." (上周末我在邮票收集展会上买了一枚稀有邮票。)
