Chinese and Catholics and Numbers
The Three Noes and the Gang of Four are examples from recent history. The Five Confucian Relationships go back a bit further, as do the Three Obediences and Four Virtues. The Four Noble Truths and the Eightfold Path are pre-Chinese. In our tradition, we have the Three Theological Virtues, the Four Sins that Cry to Heaven, the Four Cardinal Virtues, and the Seven Deadly Sins.
Applying Occam's Razor, I would say that Chinese and Catholics "love to enumerate things" simply because it makes them easier for the masses to remember. As one of the masses, it does.
