It describes the scene at that time. It should be a cold spring, but it's like early summer. Peach blossom is red and pear flower is white.
From the topic "My Shadow"
Peach blossom red, pear blossom white,
In spring, they bloom one after another.
Red is exquisite and beautiful,
White is pure and lovely.
We are also a flower,
Add luster to spring.
