Thai society is undergoing conflicts in the relationship between new generations and the elderly caused of the different frameworks of beliefs. The wisdom transfer process, an approach used in old times, is a solution to such conflicts. However, currently, it is used as a support mechanism. This research aims to develop a wisdom transfer process to ensure a good relationship between new generations and the elderly and study its efficacy. The process was applied to the elderly and new generations in Thung Samo Community, Phanom Thuan District, Kanchanaburi Province. The wisdom transfer process consists of 5 steps, namely Step 1: Agreement of local wisdom learning between the elderly and new generations, Step 2: Learning the background of local wisdom, Step 3: Learning by doing, Step 4: Local wisdom creation based on the ideas of young generations, and Step 5: Publicising the learned local wisdom achievements could boost the relationship between the two age groups, with a higher mean in the post-process. More outstanding communication between the two age groups was the key to better understanding between new generations and the elderly.
