On this field trip I have to Phetchaburi with friends and teachers. Before the trip, I had to find out about where I go and prepare food, snacks and water for the trip. At the first place I was the Chang Hua Mun royal initiative project. I have sat and listened to lecturer talk about the history of the project and view around the project.

The project has been allocated to agriculture as well. there are planting Phetchaburi local economic crops such as, phetchaburi rose apple, pineapple, coconut, lime and yam
