This activity innovatively integrated food security themes with traditional crafts, setting up three experience sessions: grain lacquer painting creation, lacquer fan making, and intangible cultural heritage food "painted rice" production. Indonesian teachers and students used dyed rice, corn and other grain particles as materials to complete 15 grain lacquer paintings that integrate Bali scenery and Chinese farming elements under the guidance of professional teachers. Among them, "Symbiosis in Rice Sea" was collected by Indonesian institutions as a cultural exchange token.
