The reason why peony noodles are more expensive than head noodles may involve many aspects. First of all, face peonies are slightly larger in size than head peonies, which may result in higher demand in the market, leading to an increase in their prices. Secondly, the eyes of facial parrots have a white ring around them, making their eyes more beautiful. This appearance feature may increase the popularity of facial peonies, thus pushing up the price.

In addition, the rarity of peonies in noodles may also be a factor in their higher price. Because face peonies are rarer than head peonies, their prices may be affected by supply and demand, where scarcity causes prices to rise.
