1. 7 kilograms of barley, 3 kilograms of tea powder, 100 grams of natural spices, and 50 grams of beef bone meal.

2. Wash and remove stones: It is best to wash the barley first to remove debris, stones, sand, etc. and then dry or sun-dry it. Roasting: Stir-fry in a clean pan over low heat until the skin is browned. Roasting must be done evenly and with appropriate force, so that the water in the barley grains can evaporate evenly and gradually, as long as it can be crushed. Crushing: Use a stone mortar or other methods to gradually crush the barley grains and tea leaves into powder.

3. Sieve: Use a coarse sieve to sift out the skin from the barley flour. Mixing: Mix barley flour and tea powder in proportion. Ingredients: Add natural spices and beef bone powder to the mixed powder of wheat and tea. Sieve again: Pass through a fine sieve once to ensure the quality when drinking.
