Sometimes, it pays to read more. I find this quite funny.

Quoted from the chinese version of a guidebook that introduces Katong and Joo Chiat.....
Many people dunno that Katong and Joo Chiat are actually 2 different places. Joo Chiat is located at Katong area... And Katong is Chow ( Zhou ) Joo Chiat's grandfather.

So there was this person who brought this topic up and question the contents of the guidebook. This was wad he said:

'After reading that guidebook, something came up in my mind - If Katong is Joo Chiat's grandfather, then, who is Katong?
The answer was found at the nxt page...
Oh, Katong is a type of tortoise found in Singapore.
So I was thinking, if Katong was Joo Chiat's grandfather and Katong is a tortoise.. den Joo Chiat is???' - By Mr Low

Ok, I shall stop here... coz i reallie cant stop luffing.
