He stayed at Hong Kong's Ritz Carlton hotel for a few days and was pleased to meet some of the fans of the Rajkumar Hirani-directorial.
"The housekeeping staff of the Ritz Carlton Hong Kong. Fans of 3 Idiots. A favourite in these parts. Bless you Raju," Boman tweeted.
The film "3 Idiots", which criticised the education system in India without being too preachy, released in Hong Kong in 2011. It also hit other Asian countries like Japan and China.
