For my first dive, I compared many places and finally chose this one, which was moderately priced at 700 yuan. We met at 8 AM, and I walked there as I was staying nearby. Because my foreign language skills aren't great, I wanted to arrive at the meeting point early, but the official location was inaccurate. A kind local Thai man helped me search for a while and then walked me there, which was only a few dozen meters away. Upon arrival, they asked if I had a diving certificate; if not, there was an additional charge of 1700 Thai Baht. Photos by the instructor cost 500 Thai Baht (optional). One of the instructors was a very meticulous Chinese woman who took care of me throughout, patiently explaining everything, so there was no language barrier. She stayed by my side the entire time underwater. It was a great experience! For ordinary people doing their first dive, spending several hours on a boat might cause seasickness, which could affect the experience. I hope my experience can help anyone considering trying diving.
