Perhaps you should try some spelling variations:
birth adding » birth timing
dan yang » daun yang, tan yang, wang yang
tao yang » yao yang, tan yang, xiao yang
ii first » ai first, 2 first, 3 first
i first » ai first, 2 first, 3 first
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) or (tao yang)) ((ii first) OR (i first)) birth adding dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((dan yang) OR (tao yang)) ((ii first) OR (i first)) birth adding dong sin ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((dan yang) or (tao yang)) ((ii first) OR (i first)) birth adding dong sin ;".
• Adding a wildcard symbol may retrieve word variants: lang ((dan yang) or (tao yang)) ((ii first) OR (i first)) birth adding dong sin ;*.
