Have you ever been to Xi ’ an ?   Yes , I ’ Ve been there several times on business trips . But I have never really seen the terra-cotta warriors as it is outside the city .   I ’ Ve heard many people saying that it is a place worth touring . I really want to see the old walls and terra-cotta warriors one day . Of course I won ’ t miss the local food either . You know , the sites interests a food in scenery , food is a key factor when visiting a place .
