　　As the last solar term of summer, Major Heat brings the year's most intense sunlight and the peak of sweltering humidity. Here at Dongying's Yellow River Delta wetlands, fireflies living in decaying grass illuminate the night; damp soil teems with burgeoning life; and sudden downpours sweep away the heat waves— All of them embody the nature's ancient wisdom of "Three Pentads".
