Correct syntax

Singapore is a / the tropical city that broke the rules.

I'm not sure what you mean - what is an example of a "rule" that has been broken?

acevalloI want to express that singapore broke the typical or the comun of the a tropical city

I'm suspicious that you mean 'typical' in place of 'tropical'. What do you say?

I also think you are trying to say that Singapore (metaphorically) "broke the rule" simply in the sense that it is not a typical city. It "breaks the mold" by being so atypical

Thanks alph, in general the tropical cities have a difficult style life for the humedity and hot weather everything deteriorates easily in singapore the life style is high level and the maintenaince is constant

Thanks calif, that is the idea, broke the rule in a way metaphorically, so could be: singapore breaks the mold of tropical cities

acevallo Singapore breaks the mold of tropical cities.

OK. I'll have to look at some maps. I didn't know Singapore was tropical.

Although I live in a subtropical city, we experience the same difficulties due to high heat and humidity. Singapore seems to be very typical of a highly-congested city located in the tropics.
