Topics can basically be divided into two general categories: (1) matters of moral principle such as unity with the mainland vs. independence or whether or not a nuclear power plant should be built, about which everyone can speak; and (2) scientific and special topics, about which not everyone can speak.
基本上分成（一）倫理的論點，例如統獨、是否要建核能電廠等，大家都可以說；（二）科學、專業的問題，不是每人都可以談。
