⛲ 涌 gush + 现 appear = things gushing into appearance, springing up everywhere
涌 — water radical 氵 + 甬 (yǒng, phonetic)
A semantic-phonetic compound: 氵 (water) gives the meaning, while 甬 supplies the sound. It originally described water gushing or welling up from a spring, and by extension came to mean any surging or swelling motion, as in waves or crowds.
