What's your favorite number and why?

Many people think the number 7 is their lucky number. Actually, personally, I prefer the number 6! In fact, the number 7 was loved by westerners earlier abroad. They think the number 7 symbolizes spiritual perfection. All life centers on the number 7 and regards it as the luckiest number! For example, a week is seven days, and it is these foreigners who make them stay up from Monday to Sunday, so they have to worship and pray on Sunday and look forward to the beginning of a new week. However, people in China think that although 7 is perfect, there is an old saying in China that "extremes meet", and behind perfection is the end! So they think the number 6 after 7 is better, and it is smooth and smooth, with beautiful things and room for improvement!
