Later on the name was changed to Tsuiheng, which is a homonym in the local dialect for Tsaikang, because, for one thing, the area was very lush and verdant (tsui), and, for another, the word heng is part of an auspicious saying which means that "all things will go smoothly."
後人因為此地山林翠綠，溪水潺潺；又在方言中，「蔡坑」與「翠亨」諧音，有萬事亨通的寓意，於是改稱「翠亨」。
