This can be pretty much seen as the end of the line for the teen sleuth cartoon series that pretty much dominated Saturday mornings for much of the late 1960's to early 1970's. Unfortunately, this follows the usual pattern of most of those shows. The kids discover a mystery that is baffling the police and try to solve it themselves. However, the main twist in this series is that the kids are all the children of the famous detective Charlie Chan, who is finally played by an Asian actor, even though it is just the voice of Keye Luke. Of course, Keye Luke played Lee Chan (aka Number 1 Son) in the movie series. However, that is probably the only thing that distinguishes this from the other teen detective series that were on at the same time. Another thing that I didn't like about it was that the kids did all the work while their father who pretty much does nothing during each episode winds up solving the mystery. Also, you know that it is a turkey when this show is pretty much used to try to sell very lame bubble gum rock songs, a la shows like "Josie and the Pussycats" and the second season of "Scooby Doo, Where Are You". Thankfully, this show only lasted one season and it marked the beginning of the end of the teen sleuth comedies.
