In Buddhism, there are well-known Mahayana Buddhism and Hinayana Buddhism. We know that Sakyamuni Buddha, Burning Buddha, Pilu Channa Buddha and Maitreya Buddha all belong to the highest fruit position under Mahayana Buddhism. The two arhats we are familiar with are added on the basis of the original sixteen arhats in India and belong to the highest fruit god cultivated under Hinayana Buddhism. Therefore, the decoration of the eighteen arhats at home is ok, and it is sincere. I hope it helps you.
