Explanation:

The word "riding a horse" in Riding the Future can be extended to "riding a horse", and horses rank eighth in the zodiac, also called "eight". At the same time, "riding to the grassland" can also be understood as "riding to the grassland", so "riding to the grassland" can be understood as "riding to the grassland" and then extended to "August 1 future"

Besides, there are other words in China culture, such as "eight directions", "eight directions" and "extending in all directions", which are ingeniously combined with the geographical concept of "grassland". Therefore, it is more appropriate to use the number 8 as a metaphor for riding to the grassland in the future.
