Short bridges, narrow stance, rounded back and concave chest, short steps, elbows close to the body – characteristic features of many Hakka Kung Fu styles like “White Eyebrow” (Baak Mei), “Dragon Style” (Lung Ying) or various branches of “Southern Mantis” (Naam Paai Tong Long).
Hakka (in Cantonese Haak Ga 客家), literaly “Guest Families”, refers to the descendants of the Han Dynasty who migrated to the Southern parts of China at a time of political unrest. They live today mainly in Guangdong, Jiangxi, Guangxi, Sichuan, Hunan and Fujian, have their own dialect and martial arts as well.
