🤷🏻 Who Am I?
I also have two separate Chinese names that had similar reading with each other. One is Xī dáyǎ (希达雅) which was used when I was in the kindergarten, the other is Xǐ dáyà (喜达亚) which was used when I was in primary school (elementary school), which is also printed on my primary school graduation certificate. Both names were given by the headmistress during my admission to the kindergarten or primary school respectively, and it's believed to be a transcription of my given name, specifically the 3rd word Hidayah and 6th word Hidayat. I have since only used Xǐ dáyà (喜达亚) when I write my name in Chinese as I use that name for a longer time when compared to the other name. In some cases, I use a Japanese name to make myself friendly when commenting on Japanese sites or discussing on Japanese forums, that is Yatsuko YASUYOSHI (安喜弥津子).
Why do you change your username?
To streamline and make it more consistent, I decide to use MNH48 as the main username and Yaya as the main nickname. Refer to me as Yaya, and when distinction needed because of existance of multiple different Yaya, refer to me as Yaya MNH48.
There was also the fact that the username muhdnurhidayat is automatically viewed as someone masculine because of the underlying spelling and the fact it contained the name of Muhammad in it. It had made many awkward moments when people keep mistaking me as male when I am feminine-leaning non-binary who kinda wear feminine all the time, like my personal favourite clothing is to wear short skirt with long socks and exposing the bare skin on thigh region, also known as Zettai Ryouiki fashion style. By changing the username to MNH48, people would not straight away assume that I'm male and will always ask me first. I'm a non-binary gendered person who uses both they/them and she/her pronouns.
What is the meaning behind MNH48?
There was a long backstory about the number 48, but the main story was of that during computer class when I was in form 1 (7th grade) of secondary school (middle school / high school) back in 2009. The processors of the computers in the computer laboratory were 32-bit, and there were issues about certain portable softwares not able to run because they were written for 64-bit processor. Without having proper computer knowledge at the time, I dumbly suggested that we "should use 48-bit" as simple middle ground between 32-bit and 64-bit, since (32+64)÷2=48. My classmates actually start to use the number 48 to tease me from the class onwards, but I take it as my lucky number and would not forget the incident.
What is the reason for using the name Yatsuko YASUYOSHI?
The family name Yasuyoshi (安喜) was chosen as I found it on certain site that claimed that the family name in that reading being near-extinct, as more people are using the same family name in different reading which is Anki. I for one don't want anything to extinct, so I decide to use it. It also contain the kanji 喜 so it relates to my existing Chinese name of Xǐ dáyà (喜达亚).
The given name Yatsuko (弥津子) on other hand is just a way to make it logical to connect with other Japanese words while retaining the important part of my native name, Ya (from the third sound of the third word Hidayah and sixth word Hidayat). In first round, I use hiragana only as the basis, with Ya (や) as the starting point. Adding Ya (や) with Tsu (つ) make it easier to attach to stuff like the honorific -chan (~ちゃん), making it Yacchan (やっちゃん) which sounds cuter and easier to pronounce than the plain Yachan (やちゃん). After that, I attach Yatsu (やつ) from earlier with the ending Ko (こ) which is something common for feminine-sounding name. When I get the full name in hiragana as Yatsuko (やつこ), I just use the principle of Ateji (当て字) and associate the kanji that has the reading, because I want name in Kanji instead of Hiragana, hence the name Yatsuko (弥津子) was born.
Why is your given name so long?
It's also a common thing that you have at least two words in your given name, a Malay person having single given name is very rare regardless gender and there are chance to be confused from next person, especially since people don't use patronymic name (last name) alongside given name (first name) because of the fact that patronymic name is private. There are also people who had even longer name, and currently, the longest registered name in Malaysia is Princess Aura Nurr Emily Amara Auliya Bidadari Nawal El Zendra Mohd Sufian where her given name, Princess Aura Nurr Emily Amara Auliya Bidadari Nawal El Zendra contains 10 words and 54 characters, and her patronymic name (revealed with permission), Mohd Sufian contains 2 words and 10 characters.
