“Tong Shui” (糖水) is a term in Chinese cuisine that literally translates to “sugar water.” However, it refers to a wide variety of sweet soups, desserts, or sweet beverages rather than plain water with sugar. Tong Shui is an integral part of Chinese culinary culture and is enjoyed as a snack, dessert, or even as a remedy for certain health benefits in traditional Chinese medicine.

These sweet soups can be served hot or cold and may include a diverse range of ingredients such as beans, grains, fruits, roots, and herbs. Each type of Tong Shui has its unique flavor profile and is often consumed for its supposed health benefits, including nourishing the body, promoting digestion, and balancing the body’s yin and yang.
