1. Present simple tense: Used throughout the answer (e.g., "choose to visit," "are always at the top of the list," "gives people a chance") to describe general habits and facts, which is appropriate for this type of question.
2. Comparative adjectives: "more affordable and convenient" uses comparative forms to compare domestic travel with other options, showing a good grasp of adjective forms.
3. Relative clauses: "Cities such as Beijing, Shanghai, and Xi’an are always at the top of the list because of their rich history and cultural significance" uses a relative clause to give reasons, adding complexity to the sentence structure.
4. Infinitive of purpose: "to connect with their own heritage and learn more about their history" uses the infinitive form to explain the purpose of traveling, which is a useful structure in IELTS answers.
