The purpose of the Schengen Convention is to abolish border checkpoints and coordinate border control outside the Schengen area. That is, the border control between six of the seven member States will be abolished, and holders of valid identity cards or visas of any member state can move freely within the territory of all member States. According to the agreement, tourists can legally visit all other Schengen countries as long as they have a valid visa in one of them.
If you are not a Schengen country, you must apply for landing visa. If the tourist country does not support landing visa, you must apply for the relevant visa of the tourist country.

Matters needing attention in outbound tourism
Passport, visa, ID card, credit card, plane ticket and other important documents should be carried with you and kept properly. It's best to make a copy of each one and put it in the handbag, and the original one in the underwear pocket.
Don't agree easily when someone checks the certificate, but report it to the team leader for handling. If the team leader is not present, you can ask the other party to show your ID card or work permit, otherwise you should refuse. If the other person is a policeman, you should also write down their ID number, badge number and car number.
A married woman should wear a ring when traveling abroad to show a strange man that you are married. In addition, don't drink drinks provided by strangers, and don't accept invitations from strangers (even if the other person is a girl).
