Perhaps you should try some spelling variations:
chung tong » chung chong, phung tung, chung kang
cheng ton » cheng boon, cheng han, chen tan
qian yan » qian jun, qian yi
yan gang » yan wang, yang guang, yang yang
kino von » kuno von
gang xi » yang xi, fang xia
von su » von seu, von sa

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 yan gang xi ((cheng ton) OR (((chung tong) OR (chung mona)))) kino von su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan gang xi ((cheng ton) or (((chung tong) OR (chung mona)))) kino von su ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan gang xi ((cheng ton) or (((chung tong) OR (chung mona)))) kino von su ;*.
