【小题2】细节题：从第三段的句子：China issues zodiac animal stamps (十二生肖邮票) every year to celebrate the Lunar New Year. They are extremely popular and a lot of collectors wait patiently for 12 years to collect a full set of them.可知收集一套生肖邮票要等一年。
【小题3】细节题：从第五段的句子：Otherwise, it is very difficult to collect stamps around the topic. You will be depressed and even lose your interest in collecting stamps.可知收集邮票的主题不能太狭窄，因为很难收集相关主题的邮票。
