Perhaps you should try some spelling variations:
tham lang » pham hang, thai bang, pham dang
nham nang » phap nang, cam nang, kha nang
tu sach » thu sach, su sach, te sach
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((tham lang) OR (nham nang)) xa hoi. hieu ((ve cam) or (va cac)) xuc va danh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tham lang) OR (nham nang)) xa hoi. hieu ((ve cam) OR (va cac)) xuc va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tham lang) OR (nham nang)) xa hoi. hieu ((ve cam) or (va cac)) xuc va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((tham lang) OR (nham nang)) xa hoi. hieu ((ve cam) or (va cac)) xuc va danh vi cua tre*.
