What sound libraries did Hong Kong movies use from the 70s-90s?

I love the punchy sounds of old Hong Kong movies from that period, but all search engines give me a blank answer on my question. I also remember hearing many sounds from Japanese TV shows in Hong Kong movies such as this Japanese police drama siren seen in a Hong Kong film( https://twitter.com/pcswpCOdZXie3Mf/status/1275379302125629441?s=20 ). This siren is almost unheard of in real life Japan due to its extreme rarity and unlike Universal and Warner sound effects, there are no clean recordings available on the internet as they are all kept from public release by TV and movie companies. What libraries did Hong Kong film studios use back then if they even managed to add rare Japanese drama sounds in even the cheapest movies like Robot Vampire? via /r/movies https://ift.tt/CbmM6vA
