Of course you have to take airplane, a bit more than three hours from Macau to Beijing by air.
The bests in Zhuhai, Shijingshan Park - Beach Park then to Qinglv Road and walk ten minutes to the statue of fishering girl. This can be finished in the morning. In the afternoon, you can walk to Jida area for shopping or you can take bus/taxi to Meixi Archway. Go to Waizai at night for seafood.
