甚至在我年轻的时候，我有点儿天真地为我的作品安排“题目”(风景画，自画像)，我很快就意识到没有主题这一问题。

Even when I was young, kind of innocently, I arranged 'subjects' (landscape painting, self-portrait) for my artworks before I soon realized that there was no such a problem as having no theme.

如果没有主题，我们就无法在建筑上做文章。

If we didn't have a theme, we wouldn't have an architectural treatment.
