Bullet train to Shenzhen from Guangzhou and Shopping in GZ

There is bullet trains from Guangzhou Railway Station to Shenzhen, but seldom. So it is advisable to take the bullet train from Guangzhou East Railway Station to the Shenzhen.
As for the shopping, I think Beijing Lu can catch you for a long time, where you can find many shopping malls and stores. The Tee Mall is a modern shopping center, where you can not only shop, but intertain yourself. As for the Shangxiajiu Pedestrain, the local snack food is very good, but it is suggested to shop there.
