忽视 (hūshì) means 'to neglect, overlook, or ignore' — it emphasizes not giving proper attention to something that matters. Its near-synonym 忽略 (hūlüè) is more about accidentally leaving something out or not noticing a detail, while 忽视 often carries a stronger sense of willful or careless disregard. 不顾 (bù gù) focuses on actively defying consequences or danger.
