using sar » using sat, using smart, using saber
using svr » using 4ir, using sat, using se
run pain » run gain
ying jin » jing ji, yang jie
yang jin » yang jie, yang jun, shang jin
han run » han rui, can run, bank run

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: (zhen OR when) zhang han run pain ((ying jin) OR (yang jin)) ((using sar) OR (using svr)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(zhen or when) zhang han run pain ((ying jin) or (yang jin)) ((using sar) OR (using svr)) ;~".
• Adding a wildcard symbol may retrieve word variants: (zhen or when) zhang han run pain ((ying jin) or (yang jin)) ((using sar) OR (using svr)) ;*.
