I recommend a travel guide for Laos: visa is convenient, transportation options include buses or planes, scenic spots include Vientiane Tower, Arc de Triomphe, etc., delicacies include glutinous rice, grilled fish, etc., you can go to the market for shopping, and accommodation is plentiful. Respect local customs. You can communicate in English and French. You can exchange currency or use credit cards. Public security is good but you need to pay attention to the safety of your property.
