May 28: A Chinese refugee and his young son carry their belongings as they exit the town of Beichuan and walk past Chinese soldiers preparing to enter the city in Beichuan County of China's Sichuan province. More than 150,000 people have been evacuated and dozens of villages emptied in case the newly formed Tangjiashan lake, located about 2 miles above the devastated town of Beichuan, bursts before soldiers and engineers can drain it.
