What shuttle bus should I take from Zhuhai airport to Xin Ching Science and Technology park

There is no direct shuttle bus lead to the park area, and you need to transfer.
Take the bus No. 504 from the airport to Wanwei Meidi Station, and right in the bus station, take the bus No. 601 B to Xipu Changtu Station. Then walk about 200 yards, you will reach the park.

If taking a taxi, the fare is about CNY100.
