1. group signing means that when you leave the country, your name must be on the list of tour groups issued by the travel agency before you can leave the country. Unless you join a group, even if you buy a ticket from them, you won't join a group, so you can rule out direct flights from Nanjing and Shanghai to Hong Kong and Macao. The easiest way to get to Hong Kong is to enter Hong Kong through the Luohu Pass in Shenzhen. There are many windows at the entrance, where you can have a group tour. About fifty or sixty yuan, you can travel freely after sending a group to Hong Kong. If you want to go to Macao, you must apply for a Hong Kong and Macao endorsement at the place where your household registration is located, otherwise you can't go to Macao. From Hong Kong to Macao, even newspaper groups can freely enter Macao. Therefore, Hong Kong and Macao suggest going to Hong Kong and Macao and then going back to the Mainland (not Hong Kong). 2. Shopping is generally indispensable when traveling to Hong Kong and Macao, and it is inconvenient to take children and the elderly with a lot of luggage to travel. Therefore, it is suggested to fly back to Nanjing or Shanghai directly from Macau after Xiamen, or to Shenzhen, Zhuhai or Guangzhou. You should have a direct train to Xiamen and a bullet train to Nanjing or Shanghai. Of course, you can also fly from Nanjing and Shanghai to Xiamen. Train and bullet train fares are fixed. Generally, there are more flights from Shanghai to Xiamen, which are cheaper. Anyway, pay more attention to websites like Ctrip, E Long and Chunqiu, and it is still possible to find cheap air tickets. There are no trains and bullet trains from Xiamen to Shenzhen. The direct flight ticket from Xiamen to Shenzhen is not cheap, but it is really convenient. Go to Shenzhen Airport and take the subway directly to Luohu Pass. Another option is a sleeper or a business bus. The bus will arrive at dawn in the daytime, but I prefer the night bus, preferably a business car or a sleeper car around 10. At 6 o'clock the next day, I went to the Overseas Chinese Society at Luohu Pass, washed at the station, had breakfast at the pass, and went to the pass to find a ginseng group to enter Hong Kong after the break. Hong Kong and Macao docks are open for customs clearance 24 hours, and there are boats. Macao can fly back to Nanjing or Shanghai directly, or go back to Shenzhen, Zhuhai and Guangzhou. Xiamen, Hong Kong and Macau are all very mature tourist cities, with beds ranging from five-star hotels to youth hostels. Some domestic individuals like to use Ctrip, E Long and Duoduo websites, while foreign individuals like AGODA website and read more travelers' comments on hotels. According to your own budget and needs, you can find something satisfactory. 5. Traveling in Xiamen, especially in the hot weather, suggests getting up early and having a rest at noon. It is suggested that Gulangyu stay at least one night and go for a walk at 5 o'clock the next morning. At this time, it is dawn, few people, quiet, birds and flowers, and the air is fresh. Go to those old buildings that are lost in the small streets! How can we appreciate the elegance of Gulangyu Island with the noisy people behind and the loud speakers and messy tour guide words? As for the paid scenic spots on the island, I only recommend Long Manor. The statue of Zheng Chenggong in Hao Yue Garden is suitable for overlooking, while Sun Guangyan can overlook the whole Gulangyu Island, but I suggest you take a ferry to the sixth floor of Lujiang Hotel on Lujiang Road in Xiamen for morning tea, or you can overlook half of Gulangyu Island and Zheng Chenggong. The beach around the island road is also worth visiting. It is best to go at 4-5 in the morning or at night. Walking, cycling and swimming are all acceptable. After 7 o'clock, there is nothing to see after dark, which is suitable for couples to fall in love. You can have a night tour around Zhongshan Road. If the old buildings in Shanghai are full of foreign flavor, then the old buildings in Xiamen are Fujian-style buildings with Southeast Asian flavor. In addition to Xiamen, only Singapore, Manila and other Southeast Asian regions have similar styles of buildings. If you like to see these old buildings, Xiamen University and Jimei School Village outside the island should go and see them. If I have time, I suggest a one-day trip to Nanjing Tulou to see Hakka Tulou. It takes about 2-3 days to get to Xiamen. Of course, you can stay a few more days. Don't dwell on any scenic spots, but slow down for leisure and sightseeing. 4. Take your children to visit Hong Kong. Disney and Ocean Park must go. Don't miss the lights, fireworks and lasers on Tsim Sha Tsui Avenue of Stars or Central Seaside at night. Getting on and off the tram at Taiping Mountain on Hong Kong Island is worth a visit. If you want to explore the life of old and new Hong Kong and Hong Kong people, you can take the tram in Hong Kong at night, which is cheap and unique around Hong Kong Island. As for shopping, eating and drinking, you can watch online raiders, there are too many. Generally, 3-4 days in Hong Kong is enough. I haven't been to Macao for many years, so I won't say much. Have a nice trip!
