正しい言い方

• 改革方案若要真正奏效，就必须触及现行体制的要害，而不能仅仅停留在边缘性的技术调整上，否则不过是隔靴搔痒，无济于事。(If the reform plan is to truly take effect, it must strike at the vital point of the current system rather than merely remaining at marginal technical adjustments; otherwise it is no more than scratching the surface and will achieve nothing.)
• 侦查人员通过对海量通话记录的系统梳理，终于找到了这个跨国犯罪网络的组织要害，为后续一举捣毁整个犯罪链条奠定了坚实的证据基础。(By systematically sorting through a vast volume of call records, investigators finally identified the organisational vital point of this transnational criminal network, laying a solid evidentiary foundation for subsequently dismantling the entire criminal chain in one fell swoop.)

避ける言い方

• 他的要害是懒惰 — while 要害 can mean a critical weakness, this use is overly blunt in casual character evaluation; say 他最大的问题是懒惰 or 懒惰是他的致命弱点; 要害 sounds too militaristic for everyday character description
