Lips are short and round, so they must be firm and straight without rolling back. When the flowers are full, they should not be suspended, rolled back or upturned. Short and round. Liu Hai Tongue and Ruyi Tongue are the best.
Lotus petals should be wider, shorter or longer, without pockets and "white peaks". That is, the petals are required to be like half an empty clam shell, concave and convex, and wrap the pistil.
