The six years of primary school life is like a richly colorful scroll, documenting the growth and changes of every student. Meanwhile, these six years were filled with laughter and tears, which were also a period of continuous learning, exploration and growth. Also, we spent this unforgettable time together on campus, leaving behind a great many precious memories. Today, we gathered here, in this familiar lecture hall, not only to celebrate our growth, but also remember this irreplaceable childhood period.
