What do you mean, "Before the Millennium tide falls, the wind rises and sails again"?

Written meaning: the tide of the Millennium has not retreated, and the wind and waves have started to set sail.

Metaphor: My ambition has not disappeared. When the opportunity comes, "sailing straight to help the sea" will go a long way and realize your ideal and ambition.

This is the novel "Sailing Before the Millennium Tide" published by Xinhua News Agency in the column "New Silk Road, New Dream".
