Example Input: In the rest of the world, China's supreme sage, Kongfuzi (K'ung Fu-tzu), is better known by the romanized name "Confucius." He was born in 551 b.c. in what is now Shandong Province in eastern China. So profound was his influence that eleven Chinese emperors made pilgrimages to the birthplace of the Great Teacher. You, too, can pay your respects at the vast temple raised on the site of his home in the small town of Qufu (Chufu), and at his tomb in the woods just to the north. The classics of Confucius, while seldom addressing spiritual and metaphysical matters, set standards for social and political conduct that still underlie many of the Chinese ways of doing and perceiving. Confucius laid great stress on the proper and harmonious relationships between ruler and subject, parent and child, teacher and student, the individual and the state. These relationships were deemed to be hierarchical and dictatorial. If the order was disturbed, dire consequences inevitably resulted. The son who disobeyed the father would bring disaster upon himself and his family, just as the emperor who defied the "mandate of heaven" or ignored the good of the empire brought ruin upon the nation. Over the centuries Confucius has suffered more changes of fortune than probably any other philosopher. Honored soon after his death as the greatest of scholars, he was later revered as semi-divine; you can still visit temples to Confucius in many Chinese cities. During the Cultural Revolution (19661976), however, he was denounced as a counter-revolutionary force. It was only after the death of Chairman Mao (1976) and the opening of China to the outside world under more progressive reformers that Confucius, too, was "rehabilitated." Unlike Confucius, about whose life many specific and even colorful details are known, the philosopher Laozi (Lao Tse or Lao-Tzu) is an enigma. Estimates of his date of birth vary by well over a century. One legend even says he taught the young Confucius. Laozi is immortalized by his book of thoughts on man, nature, and the universe, Daodejing ("The Way and Its Power"), which became the major text of China's greatest indigenous religion, Daoism (Taoism). With its emphasis on nature, intuition, the individual, paradox ("The knowledge which is not knowledge"), and the cosmic flow known as "The Way," Daoism became the religion of artists and philosophers. After the death of Confucius, the Zhou Dynasty entered a period of strife known as the "Warring States" period (475221 b.c.). <sep>Do we know the exact date of Laozi's birth?<sep>Yes
Example Output: No

Example Input: Before the mysterious disappearance of one of its passenger jets this month, Malaysia wasn't a country used to finding itself dominating headlines around the world. Some of its Southeast Asian neighbors, including Indonesia and the Philippines, have suffered devastating natural disasters in recent years and are all too familiar with the media frenzy that accompanies a major crisis. But Malaysia has largely managed to stay out of the international spotlight since its independence from British colonial rule more than half a century ago. "It is one of these countries, because of its geography, that doesn't have earthquakes," said Ernest Bower, senior adviser for Southeast Asia studies at the Center for Strategic and International Studies. "It doesn't have tsunamis. It hasn't been tested with a disaster like this." The disappearance of Malaysia Airlines Flight 370 has thrust the government into the dazzling glare of worldwide attention. And it hasn't emerged with very good grades. "I think on a stress test, they're failing," Bower told CNN's Jake Tapper, pointing to the government's coordination of different agencies and communication with other countries. China among critics Criticism and complaints have come from other countries involved in the search for the missing plane, including China and Vietnam, and from the relatives of passengers. Malaysian officials have created confusion by issuing contradictory statements on key aspects of the investigation. The majority of the people on board the plane were Chinese, and Beijing has increasingly voiced its displeasure with the search, especially after Malaysia announced over the weekend that evidence suggested the plane had been deliberately flown west into the Indian Ocean, away from its last confirmed location over the South China Sea. "The new information means the intensive search in the South China Sea for the whole past week was worthless and would never bear fruit," said a commentary published by China's state-run news agency Xinhua. "Even worse, the golden time for saving possible survivors, if any, was generously wasted." <sep>Why are Chinese and Vietnamese officials critical of the Malaysian response?<sep>Because Malaysia stated that the plane may have been flown into the Indian Ocean
Example Output: Yes
