關於the evidences of emotional or financial connection between you and your father since your childhood？
今天我爸又跑民政局去，想撤消最近辦理的結婚證，改辦74年的，被他們拒絕了，所以必須要走非婚生子女這條路了。
-If your family 戶口本 have your name and your father's name there, just 公證 this 戶口本 (not need it if your name is not there). Also, ask 街道委員會管理部門 to issue a 證明 to prove that your father is your biological father (relationship between you and your father) and prove that you had been living together with your father since your childhood and you were raised by your father, etc. If you have any photos of you and your father together since your childhood till now, provide some of these photos also. Anyway, any evidence concerning your living together with your father before you turned 18 will be helpful.
It is also helpful if you can ask your teachers in your elementary school, middle/higher school and/or college, respectively, to write a letter to prove that your father paid the tuition and fee to the school for you.
