《終於了解自由》是周興哲演唱的一首歌曲，並由他作詞兼作曲，本歌曲成為2019年最受歡迎的歌曲之一。本人把這首改編成鋼琴獨奏版本，以忠實呈現原曲的風味。
本人改編的鋼琴版本，其特色在於右手旋律採用歌唱的方式來記譜，除了方便演奏者能演奏如歌唱般的效果，也能讓唱者照著鋼琴譜來演唱歌曲，另外左手伴奏方面採用徹爾尼中階的伴奏方式，讓演奏者可以展現一般鋼琴高手的功力。
"Finally Understanding Freedom" is a song sung by Eric Zhou, and he wrote and composed the song. This song became one of the most popular songs in 2019. I adapted this piece into a piano solo version to faithfully present the flavor of the original song.
The piano version adapted from me is characterized by the right-hand melody adopting the way of singing to notation. In addition to facilitating the player to play the singing-like effect, the singer can also sing the song according to the piano score. In addition, the left-hand accompaniment adopts a thorough Czerny's mid-level accompaniment method allows players to show the skills of ordinary piano masters.
