The exchange meeting of Nanjing designers was themed "Echoes", which is the ripple of creativity and the reflection of concepts. The voices of designers all have an "echo". This echo, transcending the superficial appearance of the city, touches upon the essence of emotions. "Echo" is the contemplation of the past in the present, the echo of every move and stop of you/me/him. The font reflects the ancient city. It is the fingerprint of time, the chanting of the soul, and the lingering of the mundane world.
