Master Yao's health cream is expensive mainly for the following reasons:

1. Technology: Yaolaoye health cream adopts traditional hand-made technology, which requires more manpower and the price is relatively high.

2. Brand: Yaolaoye Health Cream is a brand of Zhengzhou chain pharmacies. Brand packaging, publicity, brand optimization costs a lot of money, increasing the original production price, so the price is more expensive.

However, it should be noted that there are some false propaganda and excessive myths about the price of Grandpa Yao's health cream on the Internet. Consumers should be rational when buying, and don't blindly believe.
