you could refer the word “define” to the requirement definition when software development. Though this time the software is Taiwan ( a vague one? :-)…) Something about how a possible (or alternative?) thinking (or reasoning) process will do the help. No need an inclusive answer. :-)…
For 4 million years — at the convergent boundary between the Philippine Sea Plate and the Eurasian Plate — Taiwan kept raising upwards, towards the stars.
… Brilliant. Tks.
