Perhaps you should try some spelling variations:
ong chong » song chong, ong cheng, hong cheng
chih hang » chin chang, shih huang, chih yung
chong shu » cong shu, chong suk
lang yan » wang yan, wang yang, zhang yan
yuan lin » duan lian, huang lin, yuan ming
hang ong » thang long, zhang hong, zhang rong
yuan li » guan li, yuan zi, dayuan li

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yuan li) OR (yuan lin)) chih hang ong chong shu ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yuan li) OR (yuan lin)) chih hang ong chong shu ;*.
