user: How much time violinist Ling Ling spent practicing each day?

assistant: <think>
In 2017, TwoSet Violin made a comedic reference to Ling Ling, a fictional violinist who "practices 40 hours a day". In an interview with Yle Uutiset, they described Ling Ling as the final boss of a video game: the Chuck Norris of violinists. Chen said they improvised the character from their comedy sketch video concerning a teenage violin student's tiger mom comparing the student to her friend's child. In 2018, they released a series of videos called the Ling Ling Workout. In these challenges, the duo play classical pieces (or contemporary music) with handicaps such as playing at double speed, with scordatura, while dancing or hula hooping, with hand positions reversed, or while upside down. Prominent violinists such as Ray Chen, Ziyu He, and Hilary Hahn have also attempted the challenge on their channel.</think>
Ling Ling is the Chuck Norris of violinists.  Her violin performance has far surpassed all living violin virtuosos today.
