Perhaps you should try some spelling variations:
dau tieng » dau tien, cau tieng, day tieng
hanh tai » thanh tai, hang tai, han tai
sang tao » hang tai
tai dau » tac dau, tai du, thi dau
so cham » so kham, co cham, so chat
tu sach » thu sach, te sach, tu cach
tao hoi » tao khoi, tao boi, tay hoi
tu sang » thu sang, tu san, tu lang
su sach » so sach, vu sach
hieu so » thieu so
soc va » loc va, doc va, goc va

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: ((tu sach) OR (su sach)) tu sang tao hoi. hieu so cham ((soc va) OR (hoc va)) hanh tai dau tieng~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) tu sang tao hoi. hieu so cham ((soc va) or (hoc va)) hanh tai dau tieng~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) tu sang tao hoi. hieu so cham ((soc va) or (hoc va)) hanh tai dau tieng*.
