有联想就好，thought-provoking，part of what art is for....

我下放农村时学会的 一 骉 三马， 马年的回忆。

If 马 symbolizes a star, 万马奔腾 would symbolize a galaxy or constellation in one spot physically or visually, equavilent to 骉; therefore, 万骉奔腾 would symbolize the whole universe filled with billions of galaxies consisting billions of stars, so you can imagine its scale and implications.

If this confuses you, it's all my fault, not yours :)
