Perhaps you should try some spelling variations:
sang dai » sang tai, lang dai, sang mai
dai hoi » dai hoc, dai hai, dai moi
hieu su » hieu sau, tieu su, hieu so
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
di cua » dai cua, doi cua, de cua
xuc va » duc va, tuc va, luc va
su cam » su nam, su cao, su can
cua te » cua tu

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 ((((sac ky) OR (cac ky))) OR (sai ky)) sang dai hoi. hieu su cam xuc va hanh di cua te~.
• Adding a wildcard symbol may retrieve word variants: tu ((((sac ky) or (cac ky))) or (sai ky)) sang dai hoi. hieu su cam xuc va hanh di cua te*.
