What to do in Phuket without going into the sea

I got hurt on the first day out at sea, and I suffered from both seasickness and sunburn, while my son had non-stop diarrhea and lost his appetite. In the morning, we bought some anti-diarrheal medicine from the nearby pharmacy. After my son took his medicine, around 10:30 am, we drove to Wat Chalong. We weren't there to pray or worship, just to look at the architecture and get a feel for the local culture. Thai temples have a somewhat European feel to them, resembling churches from the outside, adorned with Thai gold, looking quite luxurious. Since we neither believe nor worship, we left after a brief visit and headed to Phuket Town for lunch. After lunch, we strolled around the old streets of Phuket Town. The houses have a Portuguese style, colorful and particularly suitable for street photography. I took photos of my son, and he took photos of me, the best partners on a trip. I didn't buy anything here, feeling that nowadays you can find everything in China, so there's no need to haul big and small packages from abroad. Finally, we arrived at the mangrove celebrity cafe, which is right next to the hotel. This cafe is actually privately owned by the hotel. Compared to the Patong Beach where I stayed, this place is indeed much more peaceful. There are hardly any people on the beach, and it's not suitable for swimming, with many small floating plants on the water, which I couldn't identify. I sat in the open-air area, enjoying the sea breeze and drinking juice, while my son played in the sand under the sun. I can't understand why children love to dig in the sand so much; it's a puzzling pleasure.
