My parents' stomachs are not very good, and they often have indigestion and flatulence, so they have been drinking the Sun God Hericium erinaceus oral liquid, a stomach-protecting product.

I have to say that this product of their family has a really good stomach nourishing effect, so the landlord can try it.
