It is best not to change your name. Although you can apply for it and then change your ID card when changing it, it will bring endless troubles to your life for a long time.
Nowadays, you will use your ID card to do any business, including buying train tickets. All of our identity information will be entered into the public security household registration system. After you change your name, your household registration information will be changed immediately, but the public security household registration system database is not updated at all times. During the period when the public security system is not updated (it can take half a year at the fastest), the old identity will be canceled and the new identity will still be updated. If you are not recognized, you will basically be like a gangster. The new ID card cannot be used for any business. And if you opened a bank account before changing your name, once the household registration system is updated and the bank is connected to the Internet and the name does not match, the account will be frozen, and you will have to run away and keep opening household registration certificates.
Learning from the past, I hope you will think twice. To be honest, the surname Gao is not easy to choose a nice name. (I have the same last name as you). But as long as it doesn’t sound too unpleasant or outrageous, try not to change it. After all, this is a gift given to us by our elders, isn’t it? If you really don't like it, or if it affects your life, you can combine it with the horoscope and ask someone who understands it to change it. The changed name can be used in daily life. Anyway, the name is for others to call you, so try not to change your ID card.
