This is a sugar-free sweet tea because monk fruit contains a sweet element called mogrosides, which is 250 times sweeter than sucrose but has 0 calories. Monk fruit is called 罗汉果 (Luohanguo) and 长寿果 （fruit of longevity）in Chinese, so I named this tea - 长寿无疆茶 (The tea of unlimited longevity).
Put the monk fruit and Gancao slices into a spice bag then add to 2 liters of water along with the pears. Simmer on low heat for 20 minutes. Turn off the heat.
Put the dried Chrysanthemum flower into a separate spice bag. soak it in the tea for 20 minutes.
Remove the spices bags and chill the tea in the fridge overnight.
