针对 (zhēn duì) means 'to target' or 'to aim at' a person, group, or issue, often with a critical or responsive intent. Unlike 瞄准 (miáo zhǔn), which suggests physically taking aim or strategically targeting a market, 针对 is broader and can also mean 'in response to' a situation. It is less specific than 锁定 (suǒ dìng), which implies locking onto a precise target.
