Tears show the value of laughter, and the joy of harvest comes from hard work. From the Bible, sowing with tears will cheer for the harvest. The lyrics mean that tears show the value of laughter, and sowing in hard work will bring the joy of harvest. Bible is the same classic of Judaism and Christianity, which comes from Hebrew kethubhim, meaning "article" and later "scripture"; Greek Graphai, Latin Scripturoe, Chinese translation Jing.
