When a person travels with a backpack, he can find a local indigenous tour guide through the mobile APP without looking up a bunch of raiders, travel around the beautiful scenery and taste the delicious food. Traditional travel agencies and individual self-help tours are out. Make an APP with a travel agency, make an appointment with a local person who loves to travel, and be a tour guide or consultant for himself, which saves time and effort and can make friends. This is the charm of the street walker travel app, and it will be clear after use.
