At Wat Phra That Doi Kham, the first step is to pay respect to Pu Sa and Ya Sa. Locals believe that this area was once home to a giant couple named Ta Khiao and Ji Kam, who are now affectionately referred to as Pu Sa and Ya Sa. They are believed to have protected and cared for the forests surrounding Doi Kham. Thus, it is essential for anyone visiting the temple to honor these guardians of the land and forest before embarking on their journey to the wat.
