This sign-board has been placed at the front of Yee Lee’s office for over 50 years.  The sign-board is a bit younger than Yee Lee, which commenced its operations back in 1936.

The sign-board, with our Chinese name 義利 prominently displayed, has kept on alerting us of Yee Lee’s tradition from the very beginning ─ faith should come before profits.
