. He's the older brother of Chen Zhao.

. He began training to be an idol at ten years old.

. Because he was a trainee for so long, he didn't get to see his family all that much, including his little brother. His little brother is nineteen, and Xing is thirty six.

. He is Chinese, and he lived in China for nine years. By the time he was accepted by JYP, he knew some Korean, but not very much of it. So he's still rusty on his Korean; luckily, the female members in their group are fluent in Chinese.

. He has been with a total of fourteen women (Rachel included). He only had a close relationship with four of those fourteen.

Below is an account of the women he has been with, not in extreme detail, but it could make some people uncomfortable, because Xing is not an innocent man, and he has had a wicked past. So I'm just placing this warning here in case some would get uncomfortable.

. The first woman he was ever with was his childhood sweetheart, Ha Eun, whom he was with until she died at eighteen, after delivering a child.

. The second woman he was ever intimate with was Kimberly, his co-worker and part of their singing group. He was really missing his girlfriend, and before he knew it, he did something he felt very guilty about. He didn't know this until eighteen years later, but he had a child with Kimberly, Jaehyun, who was born on the same day as his son with Ha Eun, Daeshim.

. He and Kimberly both had felt bad about what they'd done, and after Ha Eun's death, even though they had the opportunity to be something more without it being wrong, they both decided that wouldn't be a great idea. However, the two of them still spent the night in each other's rooms from time to time. A weird, mutual agreement between them: they'd be nothing more than friends and coworkers, but they'd satisfy each other's longings when they had no one else to do so. (Kimberly was a part of his life in between breakups and would "help" him whenever he "needed" it.)

. Besides the two he had children with, he had eleven other women in his life— even if a few of the women were only one night flings. He isn't proud of his past, and let his fourteenth woman, whom he kept in his life, know about his past women and past mistakes.

. On the anniversary of the death of Ha Eun he was feeling very down. He ended up drinking his sorrows away that night at a bar, since he was actually at home. He drank and drank and drank, and the next thing he knew, he was in a strange bedroom with a woman he didn't know. After talking with her and deciding she was indeed worth his time, he, again, did something he should not have done with the woman. This was his third woman.

. His fourth woman was a one night stand, and they both knew they'd only ever be with each other this one time. The fifth one was another idol, and they had ended up working together. They were a couple for a couple of months before she broke it off, part of the reason being because people were getting suspicious, and she wasn't ready to lose her career for a man yet.

. At the age of twenty two he was with women six, seven, eight, and nine. Woman six and him had a couple of intimate encounters with each other, then he and woman seven spent a three day weekend with each other. Then he met woman eight, and the two of them had been drinking together, and after the buzz they ended up doing some things. He hadn't been with woman eight for more than two weeks before he cheated on her with woman nine— both women were in his life for three weeks before they found out about each other and dumped him.

. Xing's tenth woman wasn't even a single woman. She was married, but she felt trapped in the relationship. Her family didn't believe in divorce, so she couldn't divorce him without basically being disowned. But her husband was verbally abusive oftentimes, and wasn't a very affectionate man. So, when Xing flirted with her and was all charming and whatnot, she fell for the twenty three year old's seductiveness, and they did things that they should not have done, especially considering that she was a married woman. Another strange thing is that this woman was ten years older than Xing. One day, the woman's husband came home early, and he wanted to make things right with his wife. He walked into their room and found she and Xing in the act— needless to say, Xing left the place with bruises and a black eye. (Surprisingly, the man did not divorce his wife; he changed his life all around and became the man she deserved— well, he became more than what she deserved.)

. Xing was with two women when he was twenty four years old. He spent six months with one, then they broke up because he liked another woman, and he ended up with her for six months before she broke up with him after finding out about all the women he'd been with beforehand.

. When Xing was twenty five, he met another woman. They didn't become a couple or do stuff together until they had known each other for three months, and after a year, they moved in together. They stayed together up until Xing was thirty years old. He really liked this girl, and he had learned some lessons over this time, so he stayed loyal to her. Not only because he didn't want another STD, but because he knew that what he did in his past was wrong. So, he remained loyal. When he turned thirty, though, he decided he wanted to marry her, Before he could even propose, though, he found out that this woman had been seeing multiple different guys behind his back. The entire five years they had been together, she was seeing multiple different guys. So, he broke up with her, and he remained single, not planning to have another woman in his life again.

. Six years after this breakup, he met Rachel, an idol from the group Destiny's Child (the group was made up by SpamChan, and Rachel is her OC). For awhile he tried to ignore his feelings, but he ended up talking to her an awful lot, and he found himself quickly falling for her. But he ignored his heart and tried to use his brain. After several months of them talking and occasionally spending time together, he asked her out on a date, and after a few more dates, they became a couple. He shared his past with her, and she was kind and comforting about it, saying that everyone did things they aren't proud of. And honestly, that right there made him fall for her even more than before.

. Because of all his past experiences, he has HSV-2, and he has recurrent UTIs thanks to it. Every once in awhile he'll break out.
