Perhaps you should try some spelling variations:
things adding » thing adding, things during, things expanding
things using » things during, settings using, savings using
lang yan » wang yan, wang yang, zhang yan
yan yang » yang yang, yao yang, dan yang
di first » ai first, d first, i first
using » usigng, usindg, usking
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang yan yang di first ((things adding) OR (things using)) dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yang di first ((things adding) OR (things using)) dong sin ;".
• Adding a wildcard symbol may retrieve word variants: lang yan yang di first ((things adding) OR (things using)) dong sin ;*.
