I recommend a one-day tour from Guangzhou to Macau: from Guangzhou, take the high-speed train or bus to Macau. Visit famous scenic spots such as Sao Paulo Archway and Mage Temple, taste Portuguese egg tarts, pork buns and other delicacies, and buy special goods. Finally, take the high-speed train or bus back to Guangzhou to enjoy the beautiful scenery along the way.
