Please suggest me best way to reach upto Wuzhou.

Upon landing, you are suggested to take long-distance bus to get to the Garden Hotel Guangzhou. It will take around 4 hours on the way. After arriving, take a taxi to Tianhe Bus Station. The last bus schedule in this station to WZ is at 19:10. Hope you can catch it.
If not, find a hotel near to the bus station, the earliest bus in the next day is at 10:15.
