Not to be confused with Chang Chong-Chen or Chang (Tintin in Tibet).
Chang is a servant of Wang Chen-Yee in The Blue Lotus. He effectively protects Tintin from Mitsuhirato's actions and helps arrest him and his accomplices at the end of the adventure.
History[]
Wang Chen-Yee sent Chang to watch the house of Mitsuhirato. Chang saved Tintin's life by substituting the Rajaijah Juice with colored water, and Mitsuhirato's knife with a rubber knife.
Later he was chloroformed by Mitsuhirato's men, but he survived and helped the arrest of Mitsuhirato and Roberto Rastapopoulos.
