In Chinese culture, 8 also denotes the number of immortals and structure of trigrams, both of which are linked to auspicious ideas.

在中国文化中，8同样也意味着仙人的数目和八卦，都和吉祥如意联系起来。

Yang is the positive force in the universe, and there is enormous yang and very weak yin (negative force ) in the first, second, and third of the nine trigrams. So the three yang are very positive.

阳是宇宙间的正气，在九爻的第一爻、第二爻和第三爻中，阳已经远盛于阴，所以三阳的阳气极盛。
