"Huanglongdong Eye Drops" is a program that seems to be in a health park on the radio. In fact, it is a fake advertisement made by a liar. They found some "huanglongdong eye drops" made of expired herbs, which had no effect at all, but boasted that they were made of precious Chinese medicine. The radio station only cares about collecting money, regardless of the curative effect. Some radio personnel are involved in distributing black money. These medium wave health parks, friends of health and voices of health are all cheating money in the name of health. They cheated the kindness and simplicity of the elderly in rural or urban areas. Turn these old people's money into their own black-hearted money.
