Nin9 2 5ive is Joey Yung's seventh Cantonese full-length studio album, released on 29 April 2004.

The theme of the album is about life in the city, which is why the album is called Nin9 2 5ive (9-5, symbolising the average "city person's" working hours).

The character 溶 is just a shorter and more simple version of 凝溶 (溶 means Melt, while 凝溶 means Solidify).

The maintrack and first "plug/single" of the album is 一拍兩散, and secondary maintracks includes 世上只有, 夢路, and 借過.

Sand Entering the Eyes also incorporated Bossa Rosa style.
