Question: Article: By Zhang Youlv (China Daily 09/29/2008)--A manned lunar landing is China's next target when the current three-stage space program ends in the next dacade. "When our manned space program is completed, we will travel even further," Wang Zhaoyao, deputy head of China's manned space program office and Shenzhou VII mission spokesman, told a briefing in Beijing three hours after China's third manned space mission was successfully concluded yesterday. "After comprehensively analyzing the general trend of the international development of manned space, as well as realities in China, we see a manned lunar landing as a both challenging and tactical field in global hi-tech," he said. "We believe it necessary for our country to do something in this field," Wang said. He did not give a specific date for a moon landing. Wang, however, said, "Experts believe this is 'very much needed' for research into relevant (closely connected) technologies to further China's achievements in space." The 68-hour Shenzhou VII mission featured a 25-minute spacewalk on Saturday. It was broadcast live and watched by millions throughout the country. The crew's landing at a site in the Inner Mongolia autonomous region was also carried live by national television. The entire mission was pronounced a complete success. Wang said the three astronauts, were transported to Hohhot, the region's capital, and would spend the evening there. "They will return to Beijing this morning," he said. "During the course of the mission, Russian experts provided strong technical support for the EVA spacesuits. The successful Sino-Russian cooperation for this flight created beneficial conditions for more intensive cooperation between the two sides in the future," Wang said. The mission's success has paved the way for completing the second stage of the program--building a space station before 2020. Before that, a space lab will be set up in 2010 with Shenzhou X, the country's next full-crew space journey.

Question: Article: A Chinese couple tried to name their baby "@", saying the character best represents their love for the child, according to an official trying to standardize the national language. The unusual name stands out especially in Mandarin, which has no alphabet and instead uses tens of thousands of multistroke characters to represent words. "The whole world uses it to write emails, and translated into Chinese it means 'love him'," the father explained, according to the deputy chief of the State Language Commission Li Yuming. While the @ symbol is familiar to Chinese email users, they often use the English word "at" to sound it out. With a drawnout "t", this sounds something like "ai ta", or "love him", to Mandarin speakers. Li says the name is an extreme example of people's increasingly adventurous approach to Mandarin, as commercialization and the Internet break down conventions . Another couple tried to give their child a name that in English sounds like "King Osrina". Li did not say if officials accepted the "@" name. But earlier this year the government announced a ban on names using Arabic numerals and foreign languages. Sixty million Chinese face the problem that their names use ancient characters so uncommon that computers cannot recognize them _ , said Li, according to a report on the government website. One of them is the former Premier Zhu Rongji, whose name has a rare "rong" character that gives newspaper editors headaches.
Answer: Because the @ symbol sounds something like "ai ta", which means "love him" in Chinese.
