Perhaps you should try some spelling variations:
logic changes » ionic changes, luc changes
changes bei » changes being, changes b, changes big
bei daten » bei den, der daten, ii daten
yang jun » yang jui, pang jun, yang jin
wang wei » zhang wei, wang zhi
wang li » wang lei, wang lin, tang li
lang » land, long

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 bei daten ((wang li) OR (yang jun)) ((wang wei) OR (meng xin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang logic changes bei daten ((wang li) OR (yang jun)) ((wang wei) OR (meng xin)) ;*.
