The Legend of Tianding

At a certain point in the story, Li Hong will start threatening Uncle and Auntie Niu in Zhouzi Village.

Revisit them a few times by leaving the area and returning. Give them money to settle their debt, then Li-Hong will demand to know how they got the money.

Select the "Trick" option to disguise yourself as Furuyama and order Li Hong to apologise.

If you don't have the "Trick" option available, I think that you need to have unlocked the "Steal Her Away" achievement first, since you first disguise yourself as Furuyama during that cutscene.

NOTE: Make sure that you select the "Beat" option to unlock the "Coward" achievement before this one if you want to unlock both in a single playthrough. If you unlock this one, then Li Hong will stop threatening Uncle and Auntie and you'll need to restart to unlock "Coward".
