A minor can generally travel to China but may face restrictions when staying in a hotel without a parent or legal guardian. Many hotels in China require guests to be at least 18 years old to check in alone. For those under 18, a parent or guardian's presence or a notarized letter of consent may be necessary. These rules aim to ensure the safety and well-being of minors. It's advisable to check with the specific hotel and consult Chinese regulations for the most accurate information.
