After crossing Gongbei Port, go straight to the road, go straight to the bus terminal, and then take the free shuttle bus to the Lisboa Hotel, where you can try your luck. After coming out, turn right, and you will arrive at the new pedestrian street in Macau in about ten minutes. That street has many characteristics and is also a famous street. Dried meat and cakes of almost every household can be tasted for free. You can walk up a small slope and reach the landmark buildings in Macau. There are also museums and ancient fortresses nearby. You can also go and have a look. There is not much room, so you can finish reading it soon. You can also have lunch at Macau Recipe at the entrance of Xinma Road, then return to Portugal and take a free shuttle bus to Macau Pier, where there is a Golden Lotus Square, which is a memorial place for Macao's return to China. You can also visit Fisherman's Wharf, then return to the Wharf and take the free shuttle bus to the Venetian Hotel. I suggest you go to a nearby Portuguese home first. There is a Rua do Cunha near there, which also sells handwritten letters. You can buy some to go home, and then go to the Venetian, where there are artificial awnings, Pu people's performances, casinos and shops, so you can visit more. Finally, get out of the door and take the free shuttle bus to the gate to come back. This route is economical and covers almost all major tourist attractions in Macao.
It is more convenient to exchange Portuguese currency for sightseeing in Macao. There are exchange points everywhere, don't worry.
