Detailed itinerary from Shanghai to Rizhao for 3-4 days.

On the first day, you can visit Pinkou, World Sailing Base, Water Sports Center and other coastal attractions. Buy some souvenir shells or something.

The next day, you can go to Taohua Island by boat, or you can cast a net in the sea with fishing boats.

On the third day, you can swim in the sea, catch the sea at low tide and pick up things.

It's only three days in all, just relax and not be tired. Let's mainly play along the coast.

If you are watching the sea, playing on the beach, or catching the sea, I suggest you come to Rizhao. The beaches in Lianyungang are basically muddy. Sunny sea and beach are the best in the north.
