I like to know any flight from Singapore to Meixian and travelling time from meixian to Dapu by car

There is no direct flight between Singapore and Meixian and you need to transfer in Guangzhou.

In my opinion, you can transfer like this: you fly to Guangzhou first from your country directly. Then take the airport shuttle bus line 8A1 to Tianhe Coach Station. There you can find direct buses for Dapu directly. The buses for Dapu are at 08:30, 10:00, 14:30, 16:30 and 17:00.

Hope this method can help you~

Are rhis bus services express or normal n how long hour does it take to reach DAPU

The buses are normal ones and it takes around 6 to 7 hours on the road before reaching Dapu.
