"Mèngxiǎng Shìjiè" is an original Luo Tianyi song that is featured on The Second Page album. In 2013, a YANHE version of the song was featured on VOCANESE's Weibo page for some time as promotion for the newly launched group, but was later removed and is only viewable on PPTV. However, YANHE only sang using "La", rather than singing actual words.
