Hakka culture
Hakka culture () refers to the culture created by Hakka people, a Han Chinese subgroup, across Asia. It encompasses the shared language, various art forms, food culture, folklore, and traditional customs. Hakka culture stemmed from the culture of Ancient Han Chinese, who migrated from China's central plain to what is modern day's Southern China during the 6th to 13th century, and intermixed with local non-Han ethnic groups such as the Miao people. It has also been influenced by the cultures of surrounding Han Chinese groups, such as the Cantonese and the Hoklo. Having historically lived in the mountains of Southern China and being minority groups in many of the surrounding Chinese provinces, Hakka have developed a culture characterized by reservedness, stability, and frugality.
Kasha (folklore)
Kasha literally means “burning cart” or “fiery chariot”. During Japan’s middle ages and early modern era, Kasha were depicted as a fiery chariot who took the dead away to hell, and were depicted as such in Buddhist writings, such as rokudo-e.  Kasha also appeared in Buddhist paintings of the era, notably "jigoku-zōshi" (Buddhist ‘hellscapes’, paintings depicting the horrors of hell), where they were depicted as flaming carts pulled by demons or oni. The tale of the kasha was used by the Buddhist leadership to persuade the populace to avoid sin.
