Dear Brad,
I'm very glad to hear from you.In your last letter you ask about the post-80s in China.Actually I am the boy who belongs to this group.Comparing with our parents,life for us is getting much hard.The job market is tough and the house is expensively to afford.Now many girls prefer to marry with a man who owns a house and a car.Therefore,I don't think love built on house and cars is true love,and I doubt how long it will last.
As a matter of fact,though situations are tough today,a lot of we post-80s are making great efforts live a good life.I believe we will have a nice future.
Li Hua.
