蓝翔快书 (Lánxiáng Kuàishū)

Background
"Lán Xiáng Kuài Shū" is an original Luo Tianyi and YANHE duet. Throughout the song, both Tianyi and YANHE proceed to sing/rap about various household items and utilities, as well as places and automobiles. Overall, it's basically a very random song about very random things.
