Perhaps you should try some spelling variations:
tai khoi » tai khoa, mai khoi, tao khoi
cua tre » cua te, cuu tre, cua triet
xanh di » danh di, vanh dai, xanh tai
va xanh » va danh, va hanh, va anh
hieu ve » hieu va, hieu van
ky tang » ky nang, ky dang, kho tang
tai hoi » dai hoi, tai hai, tai hoe
sac ky » cac ky, sai ky
ve dat » de dat, va dat, ve dao
di cua » dai cua, doi cua, de cua
vu sac » vu sach, vu san, va sac

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: vu sac ky tang ((tai hoi) OR (tai khoi)). hieu ve dat (nuoc OR duoc) va xanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky tang ((tai hoi) OR (tai khoi)). hieu ve dat (nuoc or duoc) va xanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky tang ((tai hoi) OR (tai khoi)). hieu ve dat (nuoc or duoc) va xanh di cua tre*.
