Work

I balance leadership with hands‑on product and engineering. Selected projects I’ve been deeply involved in include:

• Youdao Dictionary Pen: The world's first translation pen employing neural machine translation (NMT) and neural optical character recognition (OCR). As a language-learning-oriented AIoT device, it has become a blockbuster consumer product in the Chinese learning smart device market. Since 2018, Youdao has sold millions of dictionary pens (as of early 2022).
• Youdao Neural Machine Translation: The YNMT project started in 2015 and launched in 2017. YNMT is an attention-based high-performance production neural machine translation engine. Compared with Youdao's earlier statistical machine translation technology, YNMT achieved much higher quality with high performance through GPU inference. Later YNMT adopted the Transformer architecture. Today, Youdao Translation is one of the world's most popular free translation services (for China and the rest of the world), serving hundreds of millions of requests every day.
• Youdao Courses: Since 2016, Youdao has provided live after-school tutoring courses for Chinese learners, later upgraded to the Dual-Teacher Live Course model. Youdao Courses is among the top providers; enrollments reached close to 500,000 in the summer of 2020 alone.
