Dried meat jerky, usually beef (牛肉干) or pork, chewy and salty-sweet, in flavours such as five-spice, spicy or curry. A packaged snack, not a cooked dish.
In Southeast Asia, 肉干 (Hokkien: bak kwa) is a popular Lunar New Year gift - sweet, grilled slices of pork. In mainland China it typically means salty beef or pork jerky.
