Perhaps you should try some spelling variations:
first thirty » first birth, first things, first three
first third » first child, first thing, first things
lang dan » liang dan, wang dan, lang lang
dan yang » daun yang, tan yang, wang yang
yang i » yang di, yang xi, yang yi
dong » doing, long, done
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang dan yang i ((first third) OR (first thirty)) adding dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang dan yang i ((first third) OR (first thirty)) adding dong sin ;".
• Adding a wildcard symbol may retrieve word variants: lang dan yang i ((first third) OR (first thirty)) adding dong sin ;*.
