She converted her 30 rai farm into a learning centre in 2006 to promote self-sufficient farming following the sufficiency economy philosophy of His Majesty King Bhumibol Adulyadej. When we dug the soil out to make a 19.5 rai pond for 130,000 fish, the soil became hard and compact. Saeng Tawan Agricultural Tourism Learning Centre is located on Phadung Phan Road about 3.5km east of Nong Chok market.
