Problem: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.

In the decades after the last voyage, Imperial officials minimized the importance of Zheng He and his expeditions throughout the many regnal and dynastic histories they compiled. The information in the Yongle and Xuande Emperors' official annals was incomplete and even erroneous; other official publications omitted them completely. Although some have seen this as a conspiracy seeking to eliminate memories of the voyages, it is likely that the records were dispersed throughout several departments and the expeditions - unauthorized by (and in fact, counter to) the injunctions of the dynastic founder - presented a kind of embarrassment to the dynasty.  State-sponsored Ming naval efforts declined dramatically after Zheng's voyages. Starting in the early 15th century, China experienced increasing pressure from the surviving Yuan Mongols from the north. The relocation of the capital north to Beijing exacerbated this threat dramatically. At considerable expense, China launched annual military expeditions from Beijing to weaken the Mongolians. The expenditures necessary for these land campaigns directly competed with the funds necessary to continue naval expeditions. Further, in 1449, Mongolian cavalry ambushed a land expedition personally led by the Zhengtong Emperor at Tumu Fortress, less than a day's march from the walls of the capital. The Mongolians wiped out the Chinese army and captured the emperor. This battle had two salient effects. First, it demonstrated the clear threat posed by the northern nomads. Second, the Mongols caused a political crisis in China when they released the emperor after his half-brother had already ascended and declared the new Jingtai era. Not until 1457 and the restoration of the former emperor did political stability return. Upon his return to power, China abandoned the strategy of annual land expeditions and instead embarked upon a massive and expensive expansion of the Great Wall of China. In this environment, funding for naval expeditions simply did not happen.  However, missions from Southeast Asia continued to arrive for decades. Depending on local conditions, they could reach such frequency that the court found it necessary to restrict them: the History of Ming records imperial edicts forbidding Java, Champa, and Siam from sending their envoys more often than once every three years.

Question:
Alan Shearer, CBE, DL (; born 13 August 1970) is an English retired footballer. He played as a striker in the top level of English league football for Southampton, Blackburn Rovers, Newcastle United and the England national team. He is Newcastle's and the Premier League's record goalscorer.
In a surprise move, late on 1 April 2009, it was announced that Shearer would become the manager of his former club Newcastle United for the remaining eight games of the season, taking over from head coach Chris Hughton who was in temporary charge while the permanent manager Joe Kinnear recovered from heart surgery, having taken ill on 7 February. Shearer stated "It's a club I love and I don't want them to go down. I'll do everything I can to stop that."  Shearer was unveiled at a press conference the following day by club managing director Derek Llambias. In explaining his acceptance of a managerial role at Newcastle at this time, Shearer stated that he would not have done this for any other club in this position, including his two other previous Premier League clubs. Amid persistent questioning regarding the permanency of the appointment, Llambias announced that Shearer was to be manager for the remaining eight games, and after his recovery, Joe Kinnear would return as manager after the end of the season. Shearer confirmed that the BBC had agreed to giving him an 8-week sabbatical from his Match of the Day role. Llambias also confirmed Dennis Wise had left his executive role at the club and the club had no plans to appoint a replacement, with Shearer stating that "the people that have moved, were moving on anyways, that had nothing to do with me". Wise's presence had previously been speculated as being a blockage to any possible appointment of a manager. Shearer accepted the surprise offer on the Monday on the condition that he could bring in Iain Dowie as his assistant. Shearer also brought in Paul Ferris to oversee club medical, physio and dietary matters. Ferris had previously worked with Shearer in his playing days, and had been at the club for 13 years prior to an earlier departure under then manager Glenn Roeder.  His first match in charge ended in a 2-0 defeat against Chelsea at St James' Park. On 11 April, Newcastle earned their first point under Shearer with a 1-1 draw with Stoke City at the Britannia Stadium with Andy Carroll scoring a late equalising goal. After a defeat to Tottenham Hotspur and a draw against Portsmouth, his first win for Newcastle came in a 3-1 victory over Middlesbrough that lifted Newcastle from the relegation zone.  On the eve of the final day of the season on 24 May, where all fixtures are played simultaneously, Newcastle faced the prospect of being relegated to the Championship, along with Hull City, Middlesbrough and Sunderland, which would end their 16-year unbroken spell in the Premier League. After losing 1-0 at Aston Villa with Damien Duff scoring an own goal, Newcastle were relegated with local rivals Middlesbrough, joining West Bromwich Albion whose relegation had been confirmed in previous weeks, while Sunderland and Hull City survived. Shearer's eight games yielded only five points out of a possible twenty-four.  Shearer did not get the manager's job on permanent basis. Chris Hughton stepped up from the coaching staff to take charge of the quest to get Newcastle back into the Premier League, which was achieved at the first attempt as Newcastle finished top of the Championship in the 2009-10 season.
