Approximately 40 percent of CUHK's undergraduate students live on campus. There are altogether 21 undergraduate dormitories that constitute the four Colleges. The four Colleges manage the dormitories under local regulations that differ somewhat.           You will share a double or triple occupancy room with local students who have expressed special interest in sharing a room with a foreign roommate. This will enhance cultural exchange and immersion into local student life. No single room is available for undergraduate international students.           Amenities in the student dormitories include:     • Modestly furnished bedrooms with telephone and network (ResNet) connection;     • Air-conditioning operated with smart cards in all rooms (central heating is not available but also mostly unnecessary);     • Laundry facilities: coin-operated washing and drying machines and clothes lines for drying;     • Shared kitchens equipped with refrigerators, stoves, boilers and microwaves;     • Shared bathrooms with showers;     • Common rooms.
