[X] Open the southwest (Lesser boost in popularity for Hanyi, may boost Weilu Reformer support in long term. Bond 1 with Meng Diu)
Only Meng contacts are not without benefit for Hanyu. She get less popularity that way, but more acceptance which will be important if in distant future. She wouldn't stay as Hanyu the Little Sister forever, sooner or later she will become Hanyu the Great Spirit and being accepted part of the land is important. So it's +2 to Hanyu vs +1 to Hanyu, delayed +1 to Hanyu and +1 to LQ.The reason this isn't hard for me is because Hanyi will come out ahead regardless. It's not like by choosing the first option we are taking something away from her. To quantify my thinking, look at it this way. We start the conversation at 0 "benefits", and we are offered two choices, one where it's +2 "benefits" to Hanyi, and one where it's +1 to Hanyi and +1 to Ling Qi. Either way Hanyi is further than where she started, and the first one helps us and leaves further cooperation open.
Ummm ... I'm almost positive he meant weeds in the metaphorical sense. Because you need "good soil" to grow a "good crop" of citizens. And sometimes "bad apples" and "weeds" need to be removed in "accidents".
