1. Zheng He's voyage to the West is a feat in the history of world navigation. Zheng He was a great navigator in the history of China and the world. Zheng He's voyages to the West enhanced the friendship between China and Asian and African countries. The historical significance of Zheng He's voyage to the West: Zheng He's fleet traded with western countries on an equal footing. Wherever the fleet went, most of them were warmly welcomed. For example, on the first voyage to Zhancheng, the king and his subjects greeted him with gongs and drums. The fleet exchanged goods such as gold and silver treasures, silk and celadon tableware for jewels, spices, medicinal materials and exotic foreign objects from various countries. Zheng He's voyages to the West promoted the economic exchanges between China and Asian and African countries. When Zheng He went to the Western Ocean, he invited countries to visit China. During the Yongle period, kings, queens, envoys and caravans from Bonai, Manzega, Sulu and other countries came to Nanjing and Peiping in China in an endless stream, sometimes with more than 500 people accompanying them. The Ming government hosted a banquet and presented many gifts, which were displayed in the Wenhua Hall. King Sulu died of illness in Dezhou, Shandong Province on his way back to China, and Ming Chengzu ordered him to be buried in northern Texas with a royal ceremony (let students see the tomb of King Sulu, located in Beiying Village, the northern suburb of Dezhou today). This is an outstanding example of the development of friendly relations between China and foreign countries in the Ming Dynasty. Zheng He's voyages to the West promoted the friendly exchanges between China and Asian and African countries. Zheng He's voyage to the West further promoted the flow of China people to Nanyang. 1one day in 924, the general manager of Beiyang warlord Pang held a chess game in Beijing to celebrate his 30th birthday, with many famous artists and unprecedented pomp. Song Bobao, a famous Japanese chess player, was invited, and Kuang Yishan, a famous chess player known as the "King of Chess in the South of the Yangtze River", also took his son Amin Bei to the chess meeting at the invitation of his close friend Gu Qinjia Guan. When Kuang Yishan, who is honest and honest, plays chess with Pang, he is unwilling to play "flattering chess". Pang is very angry and is not allowed to play chess with him. Song Bo, who longed for chess friends, found Guan Jia playing chess with Kuangyishan that night, and stumbled upon Amin, who was 8 years old, and wanted to take him as an apprentice. Unexpectedly, Song put his son in the position of "Tianyuan", but Kuang Yishan was taken away by the police sent by Pang. Song Bo successfully rescued Kuang Yishan, but it was time for his return, so he left an unfinished chess game. Before he left, Song Bo begged Kuang Yishan to send Amin to Japan in the future and train him into a chess star. 1930, Kuang Yishan sold his ancestral property and sent his son to Japan. Before he left, he gave Amin a folding fan with the words "Fenfei" written on it, encouraging him to learn chess well and make efforts to revitalize the chess world of the motherland. After Amin went to Japan, he never forgot his father's instructions and learned chess from Senchuan and other senior brothers. For him, just like his parents, his sister Ren and his daughter Ba also regard him as a relative. Soon, he fell in love with Ba and got married. After the Lugouqiao Incident, Amin was worried about the country and the people, so he reluctantly stayed at the suggestion of Pakistan. After hard struggle, he finally achieved a "sacred position." However, the Japanese army forced Amin to become a Japanese citizen. Amin said that he would rather give up his "sacred position" and quit the Japanese chess club than change his nationality. So he and Pakistani decided to flee to China. When Song Bo helped them escape, Amin was killed by the Japanese because he believed Hashimoto's lies. Ba went crazy for this. Song Bo and his brother-in-law Ntian were also implicated and forced to join the army. At this time, Kuang Yishan suffered great misfortune and shame in Wuxi, because he refused to cooperate with the Japanese army in Dazu Ozaki. His family fled under the cover of guerrillas, his wife was killed on the way, and he fell into the hands of Ozaki. Ozaki threatened to break his fingers and force him to play chess. Kuang Yishan vowed not to die and was cut off the index finger and middle finger of his right hand on the spot. At that time, Song Bo came to China as a private soldier and witnessed this tragic situation, which was very painful. After Japan surrendered, Kuang Yishan went to Japan by boat to look for Amin at 15. When he learned that Amin was dead, he mistakenly thought that Song Bo had betrayed Amin and was determined to get back at Song Bo. After Song Bo returned to China, he was down and out, desperate and drunk all day. Later, Kuang Yishan was disappointed to hear that he died in battle. After the founding of New China, Kuang Yishan carefully trained the next generation of chess players and realized his long-cherished wish of "flying hard". 1956, the Japanese Go delegation visited China to revitalize chess. Song Bo took Ren and Amin's daughter and made a special trip to visit Kuang Yishan. With guilt, he returned the ashes of Amin and Fan Fenfei, who was stained with Amin's blood, to Kuang Yishan, and told his unfortunate experience to the old chess player and relatives in a foreign country. After living in Cang Sang for 30 years, Kuang Yishan and Song Bo finally started their unfinished chess game again.
