古代阳与羊同音，羊即为阳。“三羊”依照字面来析，解释为三个太阳比较直观，即早阳、正阳、晚阳。朝阳启明，其台光荧；正阳中天，其台宣朗；夕阳辉照，其台腾射。均含勃勃生机之意。

“三羊开泰”是中国羊年春节人们互致问候使用频率最高的词汇之一，但如何解释“三羊开泰”却少有人知。一位腰缠万贯的老板2月1日农历大年初一拜年时一口一个“三羊开泰，万事如意”，但当问起“三羊开泰”的本意时，他竟然说：“是三只羊朝着太陽奔向泰山，这当然是大吉大利了。”其解释不禁令诧异，令人感到不得要领。

又询问多人，或是自称不知，或是云里雾里一通乱解，更有穿凿附会者说：“三是吉利数字，三只羊凑在一起，团结一心可开山辟路。”于是利用各种渠道查阅，方知“三羊开泰”之正解：“ 三陽開泰”。最早出自中国古代傳統文化典籍《易經》，大概意思是指“冬去春來之意”。

《漢語成語詞典》解釋：“《易經》以十一個月為復卦，一陽生於下;十二個月為臨卦,二陽生於下;正月為太卦, 三陽生於下。指冬去春來, 陰消陽長，是吉利的象徵。後作新年開始的祝頌語。”

更加通俗明白的解釋是在《易經》以正月為太卦，而古人認為這是一陰氣逐漸減少而陽氣逐漸增長。在農曆十一月冬至那天白晝最短，而往後白晝就會越來越長，因此將冬至視作「一陽」、「十二」則被稱作「二陽」，而「正月」則被稱作「三年開發」。在《易經》的64個卦名當中，“太卦”被視為好卦，所以有著「否極泰來」的成語。而且由於古代中國對"牛"和"喜"字有相同發音，並且常用以表達喜悅或慶祝的心情，所以也常見到與此相關的地名和器物上刻有'吉祥'字樣。

總結來說，“Three Sheep Open Auspiciousnesses” is a traditional Chinese idiom that symbolizes the arrival of spring after winter and the end of bad luck. It has its roots in ancient Chinese culture and philosophy, specifically in the book "I Ching". The idiom refers to the transition from cold weather to warm weather, as well as from darkness to light. In this context, it is a positive message for people to look forward to better times ahead.

In addition to its literal meaning, "Three Sheep Open Auspiciousnesses" also carries symbolic significance. According to Chinese folklore, sheep are considered auspicious animals because they represent abundance and prosperity. Therefore, when three sheep are mentioned together in an auspicious context like New Year's greetings or celebrations of special occasions such as weddings or business openings), they can be seen as a metaphor for good fortune coming into one's life.

So while some may interpret "Three Sheep Open Auspiciousnesses" literally by associating it with real-life experiences involving sheep (such as farmers herding their flocks towards higher pastures during springtime), others may see it more figuratively through the lens of traditional Chinese symbolism where sheep embody happiness and success.

It should be noted that while there may not be an absolute definitive answer on how best to interpret this phrase - especially given its widespread use across various contexts without any consistent explanation - understanding what lies beneath these words can help us appreciate their cultural richness further by appreciating both historical origins alongside contemporary interpretations which have evolved over time through generations' shared experiences.
