Perhaps you should try some spelling variations:
lang yang » wang yang, yang yang, lang lang
yang data » yang dali, yang maha
ring data » using data, being data, doing data
tell kits » test kits, tool kits
kits dong » its doing, kim dong
hoang suk » hoang vu, chong suk, yong suk
hoang sy » hoang vu

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 ((yang data) OR (ring data)) tell kits dong ((hoang suk) or (hoang sy)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yang ((yang data) OR (ring data)) tell kits dong ((hoang suk) OR (hoang sy)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang ((yang data) OR (ring data)) tell kits dong ((hoang suk) or (hoang sy)) ;*".
