Perhaps you should try some spelling variations:
things chapter » things happen, thinking chapter
lang yanling » wang yanling, wang yangming, zhang yunling
yanling yang » yang yang, ying yang
thin line » think like
yang ka » yang fan, yang yao
ka las » a las
sin » sign, sind, skin

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yanling yang ka las ((thin line) OR (((things chapter) OR (findings chapter)))) dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling yang ka las ((thin line) or (((things chapter) OR (findings chapter)))) dong sin ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling yang ka las ((thin line) or (((things chapter) OR (findings chapter)))) dong sin ;*.
