By traveling past the Tarim Basin region, the Chinese of the Han Dynasty learned of powerful kingdoms in Central Asia, Persia, India, and the Middle East with the travels of the Han Dynasty envoy Zhang Qian in the 2nd century BC. From 104 BC to 102 BC Emperor Wu of Han waged war against the Yuezhi who controlled Dayuan, a Hellenized kingdom of Fergana established by Alexander the Great in 329 BC. Gan Ying, the emissary of General Ban Chao, perhaps traveled as far as Roman-era Syria in the late 1st century AD. After these initial discoveries the focus of Chinese exploration shifted to the maritime sphere, although the Silk Road leading all the way to Europe continued to be China's most lucrative source of trade. Later, the Buddhist Xuanzang traveled from Chang'an to the west on land in his starting and returning journeys.

[edit] South China Sea

Before the advent of the Chinese-invented mariner's compass in the 11th century, the seasonal monsoon winds aided one in navigation, blowing north from the equatorial zone in the summer and south in the winter.[1] This most likely accounts for the ease in which Neolithic age travelers from mainland China could to settle on the island of Taiwan in prehistoric times.[1] After defeating the last of the Warring States and consolidating an empire over China proper, the Chinese navy of the Qin Dynasty period (221 BC—207 BC) sailed down into the South China Sea and conquered the peoples of modern-day Guangzhou and northern Vietnam (then called Jiaozhi and then Annam).[1] The northern half of Vietnam would not become fully independent from Chinese rule until the 10th century (938 AD). In 1975, an ancient shipyard excavated in Guangzhou was dated to the early Han Dynasty (202 BC –220 AD), and with three platforms was able to construct ships that were approximately 30 m (98 ft) in length, 8 m (26 ft) in width, and could hold a weight of 60 metric tons.[2]

In 403 a rebel of Eastern Jin known as Lu Xun managed to fend off an attack by the imperial army for a hundred days before he sailed down into the South China Sea from a coastal commandery. For six years, Lu Xun occupied Panyu, the largest southern seaport of that time.[3]

Travellers from Wu kingdom like Zhu Ying and Kang Tai are known to have visited Cambodia between 226-231, and reported to have met two Chinese envoys there sent by the Indian king. Although two books which they wrote have not survived, fragments remain in the Shuijingzhu, Yiwen Leiju, etc.[4]

Chinese envoys had been sailing into the Indian Ocean since the late 2nd century BC, and reportedly reached Kanchipuram, known as Huangzi (??) to them,[5][6] or otherwise Ethiopia as asserted by Ethiopian scholars.[7] During the late 4th and early 5th centuries, Chinese pilgrims like Faxian, Zhiyan, and Tanwujie began traveling by sea to India, bringing back Buddhist scriptures and sutras to China.[8] By the 7th century as many as 31 recorded Chinese monks including I Ching managed to reach India the same way. In 674 the private explorer Daxi Hongtong was among the first to end his journey at the southern tip of Arabian Peninsula, after reaching 36 countries west of the South China Sea.[9]

Chinese seafaring merchants and diplomats of the medieval Tang Dynasty (618—907) and Song Dynasty (960—1279) sailed often into the Indian Ocean after visiting ports in South East Asia. Chinese sailors would travel to Malaysia, India, Sri Lanka, into the Persian Gulf and up the Euphrates River in modern-day Iraq, to the Arabian peninsula and into the Red Sea, stopping to trade goods in Ethiopia and Egypt (as Chinese porcelain was highly-valued in old Fustat, Cairo).[10] Jia Dan wrote Route between Guangzhou and the Barbarian Sea during the late 8th century that documented foreign communications, the book was lost, but the Xin Tangshu retained some of his passages about the three sea routes linking China to East Africa.[11] Jia Dan also wrote about tall lighthouse minarets in the Persian Gulf, which were confirmed a century later by Ali al-Masudi and al-Muqaddasi.[12] Beyond the initial work of Jia Dan, other Chinese writers were accurately describing Africa since the 9th century, such as Duan Chengshi writing in 863 of the slave trade, ivory trade, and ambergris trade of Berbera, Somalia.[13] Seaports in China such as Guangzhou and Quanzhou hosted thousands of foreign travelers and permanent settlers, being some of the most cosmopolitan urban centers in the medieval world. Chinese junk ships were even described by the Moroccan geographer Al-Idrisi in his Geography of 1154, along with the usual goods they traded and carried aboard their vessels.[14]

From 1405 to 1433, a large fleet of Admiral Zheng He during the Ming Dynasty traveled to the Western Ocean (the Chinese name for the Indian Ocean) seven times. This attempt did not lead China to global expansion, as the Chinese were content trading with already existing tributary states nearby and abroad. To them, traveling far east into the Pacific Ocean represented entering a broad wasteland of water with uncertain benefits of trade. However, the British amateur historian Gavin Menzies asserts in his book 1421: The Year China Discovered the World that Zheng likely traveled as far as the Americas.

The Muslim traveler Sa`d ibn Abi Waqqas sailed from Ethiopia to China during the 7th century (650-651), establishing China's first mosque. It is also well documented that in the year 1008 the Fatimid Egyptian sea captain Domiyat, in the name of his ruling Imam Al-Hakim bi-Amr Allah, travelled to the Buddhist pilgrimage site in Shandong in order to seek out Emperor Zhenzong of Song with gifts from his court.[15] This reestablished diplomatic ties between China and Egypt which had been lost since the Five Dynasties and Ten Kingdoms period (907-960).[15] There was also the trade embassy of the Indian ruler Kulothunga Chola I to the court of Emperor Shenzong of Song in 1077, which proved to be an economic benefactor for both empires.[16]

[edit] Technique

In China, the invention of the stern-mounted rudder appeared as early as the 1st century AD, allowing for better steering than using the power of oarsmen. The Cao Wei Kingdom engineer and inventor Ma Jun (c. 200—265 AD) built the first South Pointing Chariot, a complex mechanical device that incorporated a differential gear in order to navigate on land, and (as one 6th century text alludes) by sea as well.[17][18] Much later the Chinese polymath scientist Shen Kuo (1031—1095 AD) was the first to describe the magnetic needle-compass, along with its usefulness for accurate navigation by discovering the concept of true north.[19][20] In his Pingzhou Table Talks of 1119 AD the Song Dynasty maritime author Zhu Yu described the use of separate bulkhead compartments in the hulls of Chinese ships.[21] This allowed for water-tight conditions and ability of a ship not to sink if one part of the hull became damaged.[21]
