"I Only Care About You" is a very popular song which was formerly sung by Teresa Teng. In the recent years, this song has been sung in a modern way by many new singers. They sing in their own ways, but still feels nice. This one is a new one, I just heard which was sung by a singer called Xiao Xiao (蕭瀟). She also has beautiful voice. Let's listen to her version.
蕭瀟我只在乎你
