[20] Fly Me to the Moon, the ending theme song of the Neon Genesis Evangelion anime series, served as the basis of the game's concept.

The game's song titled "Moon Trip" was composed by VOCALOID music producer Yu Jianliu (裕剣流) and Lemonjolly wrote the lyrics.

The non-mainstream status of anime and gaming culture in China posed a challenge, and that their group was only composed of university graduates also made it difficult.

[16] On 6 July, Cai Haoyu attended the GameLook Game Open Day conference in Shanghai, where he made a speech on the development and promotion of Houkai Gakuen 2.

They created a physics-based animation system; it can simulate the performance of various bodies based on physical formulas, showing more realistic character movements and destructive scene effects.

The risk is that the company may not be able to continue to launch new products to meet the needs of players or update the content of their games, and they could face the loss of users.

But we realized later on that we had greatly underestimated the difficulty of creating an open world.2016年9月，《崩坏3rd》上线並取得一定成绩之后。在接下来半年里，我们一直在思考下一款产品应该做成什么样子。整个 2017 年上半年我们都非常地焦灼，到底做什么样的产品才会让我们自己觉得 exciting、觉得 out of imagination。这又回到了我们的初心，就是我们自己想玩什么东西。那段时间，我们玩最多的是主机的开放世界游戏，这些游戏所带来的都是非常宏大的世界观和超出预期的探索体验。那么既然我们自己想玩这样的游戏，而且又愿意去做这样的游戏，我们就去做吧。就是抱著这样一个非常简单的想法，我们从 2017 年开始做这个项目。但后来我们才发现，我们大大低估了开放世界的制作难度。Genshin Impact began its development in January 2017 with the working title "崩坏4" (pinyin: Bēnghuài 4; "Honkai 4th").

[49][50] At that time, producer Cai Haoyu considered creating a new project to enhance MiHoYo's core research and development capabilities and present products with significant quality improvement to players in the future.

Other inspirations came from the random events of Grand Theft Auto, the strategy in Divinity: Original Sin, and game developer Naughty Dog.

Lumi uses Unreal Engine and motion capture technology to achieve high-quality cell-shading and rendering, as well as realistic movements, facial expressions, and skin texture.

On 14 February 2022, MiHoYo announced the launch of a new brand "HoYoverse" for markets outside Greater China, which would be operated by a Singaporean company Cognosphere Pte., Ltd. established in 2021.

The official statement said that HoYoverse's goal is "to create and deliver immersive virtual world experiences for global players", including technology research in areas such as artificial intelligence, cloud computing, and industrial capability building.

[61][62] MiHoYo responded to the press that Cai would "continue to devote himself to the research and application of cutting-edge technology, the development of new projects, and the connection of domestic and overseas R&D resources.

[64][65] Zenless Zone Zero is an urban fantasy action role-playing game with roguelike elements developed and published by MiHoYo, set in a futuristic world where a strange natural disaster called the Hollows has taken place.

Within New Eridu, players assume the role of a Proxy, an expert adept in navigating the perilous Hollow terrains, offering guidance to those who have to enter these dangerous zones.

[70] In November 2020, MiHoYo and the China Social Welfare Foundation (中国社会福利基金会) jointly launched the Yiqi Shouhu (弈起守护) charity program.

[71] On 12 July 2021, the Xinhuo Charity Program (薪火公益计划) was jointly launched by the China Youth Development Foundation and Shanghai Mihoyo Network Technology Co., Ltd.

The first phase involved Tongzi Primary School (桐梓小学) in Yunnan Province, which got support from various aspects such as hardware conditions, educational facilities, teacher training, etc.

In March, MiHoYo responded to the critical stage of the epidemic control by purchasing batches of supplies and donating them to the Caohejing (漕河泾) and Hongmei (虹梅) communities in Xuhui District.

In April, the second batch of supplies included 10,000 sets of protective equipment, 10,000 bottles of hand sanitizer gel, 40,000 N95 masks, and 100,000 pieces of disinfection wipes.

The second phase also included the construction of a waterway, flush toilet, bathroom, and solar-powered water stations for the student and staff dormitory in Bazha Village Central Primary School (巴扎乡中心学校) in Qinghai Province.

Lü Baoliang (吕宝粮), a professor from the Department of Computer Science and Engineering of Shanghai Jiao Tong University, heads the laboratory; he was also the supervisor of MiHoYo co-founder Cai Haoyu's master's thesis.

The company focuses on the research and development of HTS (High-Temperature Superconductor) magnets, plasma physics, and artificial intelligence technologies to commercialize fusion energy.

The company focuses on aerospace technology and will develop a launch vehicle and a reusable liquid oxygen and kerosene rocket engine using the raised funds.

The committee created comics and travel maps with the help of Genshin Impact material to promote Xuhui District cultural tourism landmarks.

HoYoverse stated its goal is "to create and deliver an immersive virtual world experience to players worldwide through a variety of entertainment services.
