1, add, subtract, multiply and divide, I can't count your efforts, poems and songs, and I admire you endlessly. You water our ideal flowers with the nectar of knowledge, and you nourish the beautiful fruit of our sentiment with the clear spring of the soul.

At this moment of parting, we offer our deep blessings.

3. Autumn leaves brushed gently, just like the kind words of your kind hand in those days, which gave me the gentlest comfort and the most sincere education.

On the journey of life, you lit the light of hope for me, enriched my soul and increased my wisdom. At this moment, your departure has cast a shadow over our hearts.
