2. Grasslands beside Qingqing River and Philip Burkart.
The green spring grass by the river extends all the way to the distance, which makes me miss my husband far away. Continuous: to appear continuously. There is a pun here, because seeing endless green spring grass will arouse lingering feelings for recruiters. Far away: still say "far away".
4. Appreciation: This poem describing the feelings of missing women is delicate, euphemistic, profound and touching. In particular, the poem uses the expression technique of interweaving reality and dreams, which makes the plot in the poem look like dream a dream, true or not, thus setting off the image of the protagonist who is lost in thought.
