Chia generally has a friendly and inviting atmosphere. The locals are hospitable and welcoming which could make your stay comfortable. It is a modern city with many amenities and facilities. However, like any other place, it's advisable you should always stay alert and aware of your surroundings. Avoid venturing out alone at night and be cautious with who you interact. Remember not to flash your valuable items in public to avoid attracting unnecessary attention. So, while it's not an overly dangerous place, it's not exactly the safest either.
