What do you mean by heavy wings and heavy clouds?

The heavy comparison between wings and clouds means: meet in the future struggle, let's fly together.

Source: Mao Zedong's "Farewell to He Xinlang": At present, first frost on Dongmen Road is heavy, and the moonlight on Hengtang has faded for a long time, so sad. The whistle broke my gut and I have been traveling alone ever since. Cut the thread of sadness and hate it. It should be like the collapse of Kunlun Mountain, like a typhoon sweeping the world. Heavier than wings and clouds.

Early in the morning, the east gate road is covered with frost, and there is still a half-day waning moon on the horizontal pool. It looks so sad. The whistle was heartbreaking, and I traveled alone from then on. Cut off sorrow and hate and join the revolution. Let's be like the cliff collapse of Kunlun Mountain and the typhoon sweeping the world. Meet in the future struggle, let's fly together.
