Perhaps you should try some spelling variations:
last first » act first, must first
best first » best fit, best firms, must first
liang tan » liang dan, wing tan
liang sun » liang dan, wing sun
ii chang » vii chang, yi chang, ii changes
dong di » dong sin
chang c » chang _, anhang c, chang ha

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((liang tan) OR (liang sun))) OR (dong di)) et al ((best first) OR (last first)) ii chang c ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((liang tan) or (liang sun))) or (dong di)) et al ((best first) OR (last first)) ii chang c ;~".
• Adding a wildcard symbol may retrieve word variants: ((((liang tan) or (liang sun))) or (dong di)) et al ((best first) OR (last first)) ii chang c ;*.
