Beef tenderloin refers to the tenderloin of beef.

"Liu" is a special word for Chinese food, used to refer to shaped pieces or slices of meat, with clear lines visible. What can be called "willow" is generally a place that has a moderate amount of exercise, such as pork tenderloin and beef loin. If you exercise too much, your muscle fibers will become thicker; if you exercise too little, your muscle fibers will become loose.

The meat quality of beef tenderloin meets this requirement, so it is also called "beef tenderloin".
