2009: Princess, Love Moments

Following the success of his first album, Hsiao's second album Princess was released in July 2009 with even greater success. The title rock song "Princess" was a No.1 hit for three months. This 12-song album included four songs written by Hsiao and had the chance to become the song producer for these tracks. These four songs showcased his creativity, and each one of them had its own distinguished style. He then announced his first large-scale live concert, "Mr. Rock Concert", in Taipei Arena scheduled in December 2009.

As part of his pre-concert initiative, Hsiao released in November 2009 his third album, Love Moments. This album included 10 covers of songs originally sung by top female singers. Hsiao recorded them in a live-band style. Among them, "Silent Flower" was in Taiwanese dialect, and the album's first hit song "New Endless Love" was the song he sang and got defeated on TV show, One Million Star in 2007.

Hsiao's two albums in 2009 gave him five more No.1 hits. He had six songs in top 100 on KKBOX Digital Music Billboard, and five songs in top 100 Golden Songs of 2009 on Hit FM Radio. He won the Best Male Singer Award in the 15th Singapore Golden Music Awards. In 2010, he was nominated as Best Male Singer in the Taiwan Golden Melody Music Awards.
