A question about Yu Canghai's name

[reydge]

As you see his name is Yu Canghai
But why every time I hear his name that seems they say Yu Thanghai or Yu Tanghai ?
Does C really change to Th or T in pronunciation ?

I think only Indonesian could say every alphabetical name "properly" t is "t" z is "z"🤭🤭🤭🤭
