After three years' halt, China resumes group tours to 20 countries starting from Monday. On this very day, several group tours departed from different Chinese cities to head for overseas sites. At the Shanghai Pudong International Airport, tourists gathered in the morning to check in for a group tour to Thailand's Phuket Island. A representative from Tourism Authority of Thailand Shanghai Office came to the spot to attend a ceremony for the tourists, during which she sent each tourist a phone card with local Internet access in Thailand.Photos: Chen Xia/GT
