Harbin self-help tour wants to go to Guangzhou, Shenzhen, Pearl River, Xiamen and Hong Kong. Please help me plan my trip. Thank you (for traveling in June).

Fly to Guangzhou and visit Guangzhou and the Pearl River (air tickets to Guangzhou are usually very cheap). Then from Guangzhou to Shenzhen (living in Shenzhen, because it is much cheaper than Hong Kong), visit Shenzhen. Enter Hong Kong from Shenzhen Bay Port in Shenzhen (the cheapest fare). After visiting Hong Kong, I returned to Shenzhen, from Shenzhen to Xiamen. This can save a lot of money, but the route is definitely not the shortest, it is the most economical. I have been to all the places you mentioned, and they are all good on the whole. We recommend Guandong Dabao in Guangzhou, morning tea in Nanrong Hotel in Shenzhen, Riguangyan Pie in Xiamen and Yudan Powder in Hong Kong. Everything is delicious. Have a nice trip!
