Same original meaning. Catalpa is a deciduous tree, native to China, with 6-9 meters high, opposite leaves, wide oval shape and sharp apex. Large panicle, terminal, yellow-white, with purplish spots, long filamentous capsule, flat seeds, and wood can be used for building and making wood products.
Another reason is that the hippopotamus chef is 1 1 strokes, which means 1 1.
Catalpa is also very literary, not an ordinary name.
