After the 1992 Olympics Liao joined Chinese Professional Baseball League along with the just-established China Times Eagles.

He had been gaining popularity for his excellent batting performance (Liao hit 84 home runs in only 416 games, at a speed which was only controversially surpassed by Chia-Hsian Hsieh in the Professional baseball in Taiwan history).

In 2004 Liao started to coach in the China Baseball League under 1992 Summer Olympics fellow Chiang Tai-Chuan.

He returned to Taiwan one season later to coach Taiwanese high school baseball teams, and runs a small business.

Before the Chinese Professional Baseball League's 2007 season started, the Uni-President Lions invited Liao to lecture, warning its current players the seriousness of cheating in the game.
