Origin Story
北宋理学家程颢年轻时酷爱打猎，后潜心学术，放弃了这项爱好。十二年后，他外出游历，途遇猎户打猎，顿时心痒难耐，但念及友人周茂叔曾言此爱好不会磨灭，便强压下冲动，继续前行。程颢的故事说明，即使放下爱好多年，但曾经的喜好一旦被触动，那种兴奋感仍然会油然而生。这正如‘见猎心喜’成语所描述的那样，并非简单的看到打猎而高兴，更是一种对曾经热爱的重温，一种对自身过去的认同。
Cheng Hao, a famous Neo-Confucian scholar of the Northern Song Dynasty, loved hunting in his youth. Later, he devoted himself to academics and abandoned this hobby. Twelve years later, while traveling, he encountered hunters hunting, and immediately felt an irresistible urge, but remembering the words of his friend Zhou Maoshu, that this hobby would not disappear, he suppressed his impulse and continued on his way. Cheng Hao's story shows that even after many years of giving up a hobby, the former pleasure, once reawakened, can still emerge spontaneously. This is just as the idiom 'jian lie xin xi' describes, not simply the joy of seeing hunting, but a revival of a past love and a recognition of one's own past.
Usage

Used to describe the excited mood when you see something you like, also used to illustrate that when you see others doing something that you liked in the past, you involuntarily get moved and want to try it too.
