Modify Hardcoded Text In A Compiled Linux Program

Hi all freelancers out there! I need to modify/edit some text that has been previously hardcoded into a compiled linux program. Unfortunately, we have misplaced the source files of this program so we need your help. I just need these few words in the program to be replaced. (Text In Program) -> (New Text) 空闲歌曲 -> Public Songs 预约 -> Select 点击下载 -> Download 正播放 -> Playing List is not exhaustive, just a few more texts that may need to be replaced only if you are able to change the above first.
