Perhaps you should try some spelling variations:
chih zheng » chen zheng, chih hang
zheng cong » zheng rong, zheng song, shen cong
lang yang » wang yang, yang yang, lang lang
guang hai » dang hai
shang hai » shang kai, dang hai, chang ha
chong shu » cong shu
chong suk » chong yun, cong sun, yong suk

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang yang ((guang hai) OR (shang hai)) chih zheng cong ((chong shu) or (chong suk)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yang ((guang hai) OR (shang hai)) chih zheng cong ((chong shu) OR (chong suk)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang ((guang hai) OR (shang hai)) chih zheng cong ((chong shu) or (chong suk)) ;*".
