Hii.. which station is better for me to take bullet train to shenzhen from Guangzhou?

Where are you in GZ?
As I know, there are two train stations in GZ having bullet trains for Shenzhen. From GZ East Railway Station, D-trains are operate and G-trains are from GZ South Railway Station.

In my opinion, you are suggested to take the bullet trains from East Railway Station, so that you will reach SZ at SZ Railway Station in Luohu District.
Upon reaching Luohu, you can take the Luobao Line to reach Laojie Station where you can change to Longgang Line to reach Shaibu Station.

Hope the information is helpful.

Hi.. in gz i will take frm Peasent Movement.. what's the different D & G train? As i look at Sz metro map, i only can see Sz North Railway Station..

The G-trains are faster than D-trains. The G-trains take about 36 minutes, while the D-trains take about one hour and twenty minutes.

There is no SZ Railway Station on the SZ Metro Map. On metro map, you can only find Luohu Station on Luobao Line, right? The Luohu Station is next to SZ Railway Station. If you still cannot find this place, you can ask me again.
