Fujian-based website "Straight Consume" once published an article that alleged that Zhang's eldest brother had left China and died fighting as part of an insurrection against the government of the Philippines sometime in the 1960s. According to online sources in Fujian, Zhang was said to have cut most ties with his siblings after he ascended to higher positions in the world of politics. When serving in Shenzhen, his elder brother visited him but he was said to have told his brother that he was too busy to see him. State media curiously made no mention of Zhang Xiaoyan while profiling the families of each of the members of the Politburo Standing Committee in 2013, suggesting that Zhang may not want to emphasize any connections he may have with a Hong Kong tycoon.
