Introduction: Treasure Hunting: Folk Culture in the Greater is an annual heavyweight project launched by Southern Metropolis Daily and N Video, under the guidance of the Guangdong Provincial Party Committee Propaganda Department. This project includes eight micro-documentaries and one virtual puppet animation. The series uses 4K display and interactive animation to vividly showcase the lesser-known folk culture and the stories of setting sail for trade in the Guangdong-Hong Kong-Macao Greater Bay Area.
