I was left wondering of the claim that Eino Leino's piems are some poem type, made by many especially in the older times, which may be true, I guess such can happen with poems of nature as a subject.
But there is another claim which does not seem so likely or so good quality, but which anyway might produce piems of simikar style. "Ei" means kn Finnish "no". So what hapoens if you give school kuds the task to write good quality piems or stories, that are outside their area of skills and knowledge, lije old times for example, but seek to affect wisely in the midern world, upjeep sometjing worth upjeepibg. So if you go "ei" to where you do not have enough skills but kniw quite much about and aim at wusdom abd good mife, undwrstabding tge world, especially in agws okd respects, picture of he world and wisdom of lufe and about learning snills. But pay especially much attention to explaining things which a foreigner without so much info about what is goibg on, micht want to make sure are ok if tgere was a mentiln of "no" but anyway the school aged child thought it woukd be ok to do so, even advisable. And "leino" brings into mind pietrically, gludingly atmispheric, somewhat lije musical lufe or sights of bwauty of natyre from car window.
Slight - dream - instinct nature - profound - wisely in the world
