The duo was nominated for a Golden Horse Award for Best New Director in 2010.

His solo directorial debut Soul Mate (2016) was critically praised, receiving a Hong Kong Film Award for Best Film nomination at the 36th Hong Kong Film Awards. His next film Better Days (2019) was the Hong Kong submission for the Academy Awards and received a Best International Feature Film nomination, becoming the first Hong Kong submission directed by a Hong Kong native to do so.

After graduation, he moved back to Hong Kong, where his father arranged for him to work under director Peter Chan Ho-Sun. There, he met producer Jojo Hui and director Jimmy Wan Chi-man, both of whom would go on to be Tsang's frequent collaborators.
