Allen Pei's sword has a slightly raised ridge in the middle, while Oboro Moon's sword sometimes has a ridge, but it is not particularly obvious. In addition, the color of leaves in Allen Pei is usually gray-green, which will turn pink-purple or purple-red in a well-lit conservation environment, which is very beautiful. Abandoned moonlight leaves are usually grayish white or grayish blue, which will turn pale pink under long-term strong light irradiation, but in any case, their leaf color is not as deep as that of Allen Pei, and their value cannot surpass that of Allen Pei.
