A netizen commented, if an official remembers he was previously "a poor boy," it means he understands the people's weal and woe.
For Zhang's native villagers, however, the person behind the big name remains almost a stranger, as he seldom returns to Panjing, where his brother still lives.
As a member of the top leadership, Zhang said after his promotion that he is ready to continue to be under the scrutiny of the people.
"If anybody comes to you for favor under the name of my family, relatives or friends, please never hesitate to refuse him or her," Zhang was quoted as saying to senior officials who welcomed him to lead to work in Shandong.
