Literature Reference: 《诗经·小雅·鹿鸣之什·采薇》：'采薇采薇，薇亦作止。曰归曰归，岁亦莫止。靡室靡家，猃狁之故。不遑启居，猃狁之故。采薇采薇，薇亦柔止。曰归曰归，心亦忧止。忧心烈烈，载饥载渴。我戍未定，靡使归聘。采薇采薇，薇亦刚止。曰归曰归，岁亦阳止。王事靡盬，不遑启处。忧心孔疚，我行不来。' Plucking the ferns, plucking the ferns, the ferns have just sprouted. Saying 'return, return,' yet the year has not ended. No home, no family, because of the Xianyun. No time to rest, because of the Xianyun. Source from 'The Book of Songs·Xiao Ya·Lu Ming·Cai Wei'.
