Reduplicating adjectives (AABB)

Structure AB → AABB (干净 → 干干净净)

A two-syllable adjective (AB) can be doubled to AABB for vividness and a fond or intensified nuance: 干净 → 干干净净 ("nice and clean"), 高兴 → 高高兴兴 ("really happy"). They often take 的 (as a modifier) or 地 (before the verb). It paints a livelier picture than the bare adjective.
