Perhaps you should try some spelling variations:
start thinking » abstract thinking
leasing und » learning und, clearing und
nising und » mining und, timing und
yan ning » wang ning, yan liang, yang jing
li start » i start, big start, ki starkt
ning li » ling li, liang li, qiang li
wang » wing, wan

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: (wang OR lang) yan ning li start thinking ((nising und) OR (leasing und)) sind ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR lang) yan ning li start thinking ((nising und) or (leasing und)) sind ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR lang) yan ning li start thinking ((nising und) or (leasing und)) sind ;*.
