How much is the deposit for Qingdao to go to Korea with a group?

If it doesn't involve working outside, you can go directly to the group club, usually with a deposit of 30,000 tickets per person.

If subcontracting is involved, every middleman has to make a little bet. Generally speaking, you can't afford to travel if you gamble more than 80 thousand.

So I suggest you go directly to the tour group. If the information is good, you can even charge no deposit.
