[1/3]The travel route in Guangdong and Hong Kong could be separated into two routes. One is east, and one is the middle of Guangdong. Why? There are three major Han Chinese subgroups in Guangdong. One is Cantonese (广府人), one is Hakka (客家人), and the third is Southern Min people (闽南人). Each of them has its own languages, cultures, and locations. In geography, Cantonese lives in the middle of Guangdong, where the area is called Pearl River Delta (珠江三角洲), major cities are Guangzhou, Foshan, Dongguan, and Hong Kong. And the Hakka people live in the area between the Pearl River Delta and the Teoswa area; the Major city is 梅州 (Meizhou). And the third is the Southern Min areas, including the Teoswa area, Swabue, and the Leizhou Peninsula. If you want to feel the special local culture, the most special is the Teoswa area. Other cultures have almost missed, just like any people in China, so it's nothing to suggest. Only their languages are preserved. But if you travel for other things, you could go to the Pearl River Delta. The things and cultures of Meizhou are always mixed Cantonese and Teoswa, even the language. So, Meizhou, the Hakka city, is not suggested. And the Leizhou Peninsula is not suggested as well, since people usually go there for Hainan Province. The first route is Guangzhou -> Shenzhen -> Hong Kong, mainly for modern things and some Cantonese culture. Guangzhou and Shenzhen are the top cities in China, where you can see many tall buildings. There are still some attractions for traditional Cantonese culture in Guangzhou, but not many. The most famous Guangzhou attractions for Chinese are 长隆, where you can spend your holidays.
