After spending 20 years in search of a Chinese song his mother was fond of, a Congolese cab driver in South Africa finally found the foreign language tune! All thanks to a Taiwanese couple.

In an effort to find the song his mom once dearly loved, he used to ask all his Asian passengers if they knew the song, only humming the tune to them since he didn’t speak the language but all in vain until only recently when the tourist couple recognized the tune and helped him find it online.
