Objective analysis relies on clear rules. Regardless of whether subjective analysis and objective analysis are contradictory, objective rules should be strictly followed.
There is an ancient Chinese saying that goes"Teaching people to fish is better than teaching them to fish",说的是传授给人以知识,不如传授给人学习知识的方法。道理其实很简单,鱼是目的,钓鱼是手段,一条鱼能解一时之饥,却不能解长久之饥,如果想永远有鱼吃,那就要学会钓鱼的方法。同样的道理,在炒黄金的投资中是一样的!
