燎原烈火liáo yuán liè huǒa blazing (/spreading/raging) prairie fire
❍ 恶之易也，如火之燎于原，不可乡迩，其犹可扑灭？(《左传·隐六年》)The evil issues of enmity develop easily,as when there is a fire blazing on a plain. It cannot be approached,and still less can it be beaten out. 燎原烈火liáo yuán liè huǒ燎：烧；原：原野。原指像烈火在原野上燃烧一样，使人不能接近。现多比喻不断壮大、不可抗拒的革命力量。a blazing prairie fire, raging flames |
