The Zheng Family, also known as the House of Koxinga was founded by Zheng Chenggong, or also known as Koxinga. He was a Ming Loyalist that fought against the Manchu Qing Conquests, and nearly took Nanjing, which had he did, it would've interrupted the supply route of the Grand Canal leading to possible starvation in Beijing caused such fear that the Manchus considered returning to Manchuria and abandoning China according to a 1671 by one account. However, Koxinga's forces were unable to maintain a complete encirclement, which enabled the city to obtain supplies and even reinforcements, and Koxinga was defeated.
Koxinga would turn to the island of Formosa (Now Taiwan) and fought the Dutch and established a stronghold of Ming Loyalists that would become the Kingdom of Tungning. It became the last bastion of Ming Loyalists and ethnic-Han Chinese culture after the Manchu Qing Conquests. At their height, they had a vast trade network in East Asia, and controlled some ports on the mainland. They had great ambitions, and during the Three Feudatories revolt, tried to make a go at retaking coastal cities on China, but failed. Eventually, the Qing conquered the Kingdom of Tungning in 1683.
So, what if Koxinga was able to take Nanjing, forcing the Qing back into Manchuria, and reclaiming China for the Ming Dynasty? However, later down the line (Probably not in Koxinga's lifetime), the Ming Emperors did something that loses them legitimacy (Throwing it out there, but maybe converting to Catholicism that anger traditionalists; Some of members of the Ming Dynasty did become converts near the end), and the Ming Dynasty is overthrown...
Enter the Zheng Family, who were the descendants of the heroes that saved China from the Manchus. What if the House of Koxinga takes over China by the end of the 17th Century, establishing a new Zheng Dynasty of China?
