Cha Cha Hui is a 2019 Nepali comedy drama film directed by Samten Bhutia, a filmmaker who had earlier gained attention for the critically praised film Taandro, and written by Sijan Dahal and Sandesh Aryal. The film was released in theaters on 22 November 2019 with a runtime of approximately 2 hours and 3 minutes, and it was produced under the banner of AGL Entertainment. The film attempted to bring to the Nepali screens the classic "comedy of errors" style of filmmaking, with a loose, fast-moving plot about friends, gangsters and a mysterious book.

The story opens with two inseparable friends, Prem and Bhola, who are migrant workers living in Hong Kong. In a chance meeting, they encounter the stranger Shyamlal, who gifts them a book of poems and encourages them to return to their homeland. What the friends do not realize is that the book is wanted by ruthless characters across the country, and as soon as they land in Nepal, they find themselves pursued by taxi drivers, hotel managers, police inspectors and goons, all desperate to get their hands on the book. The film takes the audience on a chase from Kathmandu to Pokhara and then into the mountains of Mustang, hiding the truth about the book along the way.

In the course of the chase, Prem falls in love with Sangeeta, a local girl from the Mustang village of Marpha whose family runs a homestay business, played by the newcomer Miruna Magar. The supporting cast is filled with experienced artists: Aaryan Sigdel plays Prem, Bholaraj Sapkota plays Bhola, Maotse Gurung appears as Shyamlal, with Prakash Ghimire, Janak Khakurel, Pushkar Gurung and others in supporting roles.

The film drew mixed reviews. Critics acknowledged that the premise of a comedy built around a mysterious book was promising and that the film had the spirit of classic comedy, but they criticized the loose screenplay and the slow unfolding of the plot. Some reviewers were strongly critical of the film's treatment of women, with its dialogue and item song drawing criticism in the Kathmandu Post review.
