At the end of the Ming Dynasty,Zheng Cheng-gong's navy,based in Xiamen and Jinmen,became an important force in the southeast coastal areas to fight against the Qing Dynasty and restore the Ming Dynas-ty.Zheng Cheng-gong took the"rejuvenation and recovery"of the Ming Dynasty as his own responsibility.If he wanted to forge ahead in the struggle against the Qing Dynasty,he had to face two strategic choices:the Northern Expedition and the Southern Expedition.Due to the inherent strategic disadvantage and the three failures of the Southern Expedition,Zheng Cheng-gong was inclined to the Northern Expedition in his choice of anti-Qing strategy.In the eighth year of Yongli's reign(1654),Li Ding-guo invited Zheng Cheng-gong to send navy to attack Xinhui,Guangdong,in an effort to achieve the convergence of the anti-Qing troops in the southwest and southeast.Zheng successfully overcame the unfavorable factors,decided to launch another Southern Expedition again,and sent General Lin Cha to lead the navy.However,Lin Cha worried about the risk of coastal navigation and the encirclement of the Qing army in eastern Guang-dong,and lacked the way to contact the friendly forces in time.He dared not to sail south quickly,so as to avoid penetrating alone into Guangdong province.At last,Lin Cha also missed the opportunity to meet with Li Ding-guo,resulting in caused the delay in joining forces with Li Ding-guo's.
