Yuezheng Longya VOCALOID4 | Songs Albums Notable Originals

Yuezheng Longya (Simplified Chinese: 乐正龙牙; Traditional Chinese: 樂正龍牙) is a Chinese VOCALOID developed and distributed by Shanghai HENIAN Information Technology Co. Ltd.. He was released for the VOCALOID4 engine in June 2017.

Longya was a runner up entry to the first "VOCALOID™ CHINA" contest in 2012 which was held for choosing the design of the first Chinese VOCALOID, and he was a Vsinger supporting character for three years before being confirmed for a VOCALOID release.[1]

He was voiced by the Chinese singer and voice actor, Jie Zhang (张杰; Zhāng Jié), who was selected based on suggestions from Chinese VOCALOID fans.[2]


According to the short animation series promoting VOCALOID CHINA, Longya is Yuezheng Ling's older brother and the heir to the Yuezheng corporation. He has an agile mind and many people look up to him. Like his sister, he is straightforward, but he also possesses the ability to make important decisions correctly and has the strong aura of a leader. His weakness includes troublesome issues, and the only time he's not bothered is when they are related to his younger sister. He is very protective of Ling and can become slightly hysterical when dealing with situations related to her.[3]

In June 2016, additional information about Longya was presented. He is a postgraduate financial student and studies at Ling's school as they share the same campus. He is usually busy since he will take on the family business after he graduates, but still sets aside time for band practice in which he is the leader and drummer. He often disappears whenever trouble occurs, but always returns to clean up the mess. He becomes very intense while playing the drums and people call him "Drum Destroyer" for some reason.[4]

According to Shanghai HENIAN's official website, his birthday is October 2. He is listed as a Libra.[5] His signature color is #006666.[6]


His original name was Yayin (牙音), however, this was dropped because it was written in a Japanese naming style rather than Chinese.

The surname, Yuèzhèng (乐正), comes from the governor of music during the Zhou Dynasty. The existence of this surname was proven when two historical books (《元和姓纂》&《尚友录》) state that: the "Zhou Dynasty's 'Yuèzhèng' Position was used as a surname", therefore hinting that the name existed as early in Zhou Dynasty which was more than 2,600 years ago.

After the Zhou took over the Chinese empire, the positions of the governing system were used as surnames. During this time, there was a head position called "Yuèzhèng", which was responsible for music and melodies at the palace. Any descendants of this governor would bear the same surname.

During the Zhou Dynasty, people took great measures with politeness and rituals. The Yuezhengs were heavily looked upon by the emperor and the standard of music can directly affect a country's impression to the outside world.[7]

"Lóng" (龙) means "dragon" in Chinese, while "" (牙) means "teeth", "tooth", or "fang". Combined, his first name means “Dragon's teeth”.


The design was originally drawn by aya, but was refined and redrawn by Chinese illustrator, ideolo.

In his debut design, located on Longya’s gold belt, there is a charm with the Devanagari letter "ट" (ṭa). This represented the "Wood" element, the "East" position, the color "Green", and the "Spring" season. Its Chinese equivalent is "角" (jué), which is one of the 5 Traditional Chinese melody characters. It corresponds with E (mi).[8]

Longya received a new design for his VOCALOID4 release.[4] His arm-warmers were replaced by a long-sleeved white shirt with stylized designs at the cuffs, and black fingerless gloves. His gold and green belts were removed. The Devanagari character is located on the buckle of his black belt and on the back of his right glove. On his chest is a long gold ribbon. His boots are in a different style, and his right boot has two green straps while his left boot has one green strap followed by two white straps. He no longer has the pouch from his old design and the collar at his neck is more open. His headphone design was changed slightly.
