What bus should I take from Tianbei to Ramada Plaza in Shenzhen?

Longgang Line → Central Ring Road → 3 16 Road

Get on the Longgang Line at Tianbei Station (direction of Shuanglong), get off at Buji Station, get off at the central line of Buji Station (direction in front of the bay), get off at Minzhi Station (exit B), walk 100 meters, get on at Zhi Min subway connection station, and get off at 3 16 Luzhimin post office station, and walk for 280 meters.

I hope it helps you.
