Perhaps you should try some spelling variations:
logic changes » ionic changes, luc changes
changes der » changes due, changes did, changes do
yang jin » yang jie, yang jun, ying jin
wang wei » zhang wei, wang zhi
wang li » wang lei, wang lin, tang li
lang » land, long
daten » datin

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang logic changes der daten ((wang li) OR (yang jin)) ((wang wei) OR (meng xin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang logic changes der daten ((wang li) OR (yang jin)) ((wang wei) OR (meng xin)) ;*.
