Is there any singing method in the poems praising Lei Feng?

Yes

"Ah. Lei Feng: Who doesn't love pure kindness, who doesn't want selfless dedication, who can really do it? On the materialistic street, who has a conscience to sweep the floor and treat honesty as ignorance, ah. Lei Feng, I stand on tiptoe to look at you. Where is your soul? It is your instinct to help others. Selflessness is your gift. Serving the people is your highest realm. Where your figure appears, there is enthusiasm and smile. Where seeds are sown, there is selflessness and kindness. Lei Feng, who doesn't miss your previous years and who doesn't expect you to come back again.
