Every city has its own unique flavor and customs. I suggest that you can slowly arrange the tour plans of various places according to your actual situation. It is best to travel by yourself, but it is not good to travel with a group, or to initiate a group trip with a donkey friend in the same place.
In the choice of places, too famous places often only look at people's heads and don't look at the scenery. You can choose some second-and third-tier cities to see the scenery without spending too much money.
Huaiyang cuisine is very famous in the Yangtze River Delta, with bright red color, slightly sweet taste and thick soup.
West Lake Vinegar Fish, Dongpo Meat, Lion Head with Crab Powder, Shanghai Tangyuan, Taiji Cuisine, Jiaxing Zongzi, Zhenjiang Vinegar, Ningbo Tangwan, Shaoxing Yellow Wine, Nanjing Salted Duck.
What matters when traveling is not external things, but your mood and traveling companions!
