Long waited

I will be out of country for 10 days starting from 12 Nov. I have to
make use of my very limited holidays that left before I start to
plunge my head into another study which will probably has no holiday.
Where am I going though? Here is the hint, the below was what my brother
likes to sing in front of my face right after I planned this.
"北京欢迎你, 欢迎你来买东西."
