Perhaps you should try some spelling variations:
long sein » long span, long pulsein
sein dann » sein kann, sein das, bin dann
ying jin » jing ji
yang jie » yang jui, yang xi, yang jun
yang jin » yang jun, shang jin, wang jing
dann yi » dann bin
yi chen » jui chen
yang yi » yang xi, yang jui

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: long sein dann yi chen ((ying jin) OR (yang jie)) ((yang jin) OR (((yang yi) OR (yang di)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long sein dann yi chen ((ying jin) or (yang jie)) ((yang jin) or (((yang yi) OR (yang di)))) ;~".
• Adding a wildcard symbol may retrieve word variants: long sein dann yi chen ((ying jin) or (yang jie)) ((yang jin) or (((yang yi) OR (yang di)))) ;*.
