Perhaps you should try some spelling variations:
liang tan » liang dan, wing tan
liang sun » liang dan, wing sun
first yeo » first year, first do, first cfo
dong di » dong sin
la last » a last, la liste, als last
first e » first _, first 4, first a
chang c » chang _, anhang c, chang ha

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((liang tan) or (liang sun))) or (dong di)) et la last ((first yeo) OR (first e)) chang c ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((liang tan) OR (liang sun))) OR (dong di)) et la last ((first yeo) OR (first e)) chang c ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((liang tan) or (liang sun))) or (dong di)) et la last ((first yeo) OR (first e)) chang c ;*".
