He said he would take his daughter to Tiananmen once. Many people asked him to sign it, but he didn't. Daughter asked him why he didn't sign, and then Zhang Tie-Lin didn't answer. He stepped forward and signed them one by one. As a result, because there were too many signatures, the father and daughter did not finish visiting Tiananmen Square. My daughter will know why Zhang Tie-Lin didn't sign it just because she wanted to spend more time with her daughter. Grandma Huang is still very considerate, hehe.
