The phrase 第一手 (dai6 jat1 sau2), literally “the first hand”, can be used to mean the first to use/own/etc. For example, my neighbors had been living in their house for 50+ years, and my father realized: 佢哋係(they are;keoi5 dei6 hai6) 第一手.
The one (一) can be exchanged for other number values to indicate second hand, third hand, and so on.
