In addition, you can also prepare a small gift with the travel agency logo as a quiz prize! You can do anything! For this song ... for this song.

You can also guess riddles ... you can prepare some local souvenirs ... which are cheaper ... and you will get prizes if you guess correctly. ..

You can also look at the car number of the car in front and let the corresponding tourists perform the program!
