Cha Guo, or tea cake, is a traditional New Year's snack and sacrificial offering of the Hakka people in the rural areas of the New Territories in Hong Kong. Its production skills have been listed in the first intangible cultural heritage list of Hong Kong. Cha Guo contains rich historical connotations. For over a thousand years, the Hakka people have migrated from the Central Plains to other parts of China and overseas. Whether in daily meals or during festivals, Cha Guo fully embodies the essence of Hakka cuisine and culture. In Hong Kong, influenced by Cantonese culture, people often eat Hakka tea cake made with chicken shit vine during the Qingming Festival, also known as "Qingming Zai".
