My collection
I have been collecting stamps and famous paitings for over ten years.I like stamps a lot,and from collecting stamps,I got a lot of precious knowledge.I'd like to invite you to have a look at my collection on stamps sometime.
Also I have been collecting old paitings for these years.I like chinese history best.As we
all know,China is a developing country with over five-thousand-year long history.We have
been awere of it in many ways.However,I'v learnt a lot of knowledge on chinese history from
collecting old paintings.Much money as I'v paid for old paintings,I'v been getting a lot indeed.
Collecting something in your sparetime is good hobby.We can obtain something valuable.
