Dear David,
I'm happy that you're interesting in our flea market and here is a brief of introduction of it.
To raise students' aware of making the most of used things, the Students' Union held a flea market on campus recent. The event attracted a crowd from the whole school, who come here to sell, purchase or swap used goods with their schoolmate. On the market, you could find vary things, from second-hand textbooks, magazines to CDs, bikes or clothes at a lower price.
In my opinion, the flea market not only provides a platform save resources but also helps students learn some practical skills, where may be useful for their future job hunting.
Yours,
Li Hua
