More than 60,000 nurses who have worked for at least 30 years were conferred with certificates and badges of honor on May 12, the International Nurses’ Day. The certificate of honor bears the inscription "Industrious work, glorious position". The badge in golden color has an oil lamp in the center, with 30 flower petals on the rim, signifying nurses’ glorious self-sacrificial spirit just like British nurse Florence Nightingale, "The Lady with the Lamp".
