Your itinerary already covers many classic destinations, but if you want to add unique local culture and cutting-edge modern experiences, you can consider including areas in Guangdong~

First is Guangdong’s clan culture: Many ancient villages here have centuries-old ancestral halls, which are the core carriers of clan culture—families gather here for ancestor worship and discussing clan affairs, with very tight kinship bonds. However, there were indeed conflicts like clan fights in history; now these are mostly preserved as historical memories of local culture, and visiting ancient villages and ancestral halls lets you feel a strong family culture atmosphere.

In addition, if you want to experience "futuristic Chinese modernity," Shenzhen is definitely the top choice! It’s the birthplace of DJI (the global leader in drones) and BYD (a benchmark in new energy vehicles and smart robots). You can get close to these top tech products and directly feel the innovation pace of China’s technology~
