i am staying in guangzhou,near zoo station, i need to travel to shenzhen Hubei station

At Zoo station, take metro line 5 to GZ Railway Station. There you can take a high speed train to Shenzhen Luohu Train Station. After that, walk to Luohu metro station to take Luobao line to Grand Theatre to use Shekou line to Hubei Station. It is around 3km between Luohu and Hubei stations, so you can also take a taxi to get there.
