Pan Farm was established in 1974, and it is the pioneer of the Four-Branch Creek Hongren duck eggs. After 30 years of expansion, the farm now produces Hongren duck eggs, hot spring preserved eggs, and hot spring salted eggs. The farm also offers West Indian cherry juice, jam, and fruit wine. In collaboration with the National Museum of Marine Biology, it offers ecological explanations of the farm and DIY hot spring salted egg tutorials.
