Perhaps you should try some spelling variations:
fordern das » fordern als, fordern am, formen das
pong klang » port klang
formen lam » formen im, formen a, formen ab
qian pong » qian rong, qian wang
klang iii » klang die, zwang iii
shang hai » shang kai, dang hai, chang ha
hong hai » zhong tai, dang hai, hong tan

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: qian pong klang iii ((formen lam) OR (fordern das)) david ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian pong klang iii ((formen lam) or (fordern das)) david ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: qian pong klang iii ((formen lam) or (fordern das)) david ((hong hai) OR (shang hai)) ;*.
