For the past 30-odd years點解?

For the past 30-odd years = 在過去30多年

For the past 30-odd years, Treasury secretaries have generally focused on G7 conferences.

在過去30多的年，財政部長通常會集中注意於G7會議。


You use this if you cannot say exactly how many years, so you just use "30-odd" years to signify that it's 30+ years.

如果你不可能正確地說30幾多年，你可用" 30-odd" 來代表30多年.

For example:

You can say "I've been watching this city grow for 20-odd years and it seems nothing has changed."

Please note that you use 30-odd when it's more than 30 years but you're not exactly certain 30 + how many years. If it's around 30 years, could be less, then you would use "around 30 years". Only use "-odd" if it's more than that number.
