The official English title of 《談情說案》 is "The Mysteries of Love".
The main purpose of Sales Presentation clips is to attract sponsors, so it makes perfect sense to show many Raymond scenes.
Personal Note: OMG!!!! I almost died!!! :D I had to miss the last half of "The Simpsons" to watch this Sales clip! So good! Fungyi fans, prepare yourselves!!!! :) Tavia is super cute!!! Ma Ming is super hot!!! Bernice's bare back scene!!! Wow!!!
