The first entrance is the preface hall. On the wall facing the entrance is a huge V-shaped relief, which symbolizes the victory of the Chinese people in the War of Resistance Against Japan. The above fists and weapons show the strong fighting spirit of the anti-Japanese army and people in Dongjiang to resist foreign aggression. The undulating relief on both sides symbolizes the meandering water of the Dongjiang River. On the left, the people of Dongjiang rose up against the Japanese aggressors, and on the right, the heroic killing of the enemy by the Dongjiang column. The relief is made of red sandstone with Dongguan regional characteristics. The gray cement wall above the relief is inscribed with the song of Dongjiang Column. There is also an electronic sand table in the preface hall, which can intuitively understand the range of activities of the Dongjiang column.
