"What do you keep under the ground?"

Translation: Apa yang kalian simpan di bawah tanah?

[Hanifa728573]

Kalian should be interchangable with kamu and anda, it's not wrong to have those other pronouns instead

[Rick392366]

You're right, it's not wrong to use "kamu", "Anda", they are also accepted translations.

[ZiadAbdat1]

actually "kalian" is plural, while "kamu" or "anda" is singular. "Kalian" is like "They", but I would prefer translate is as "you guys"..

Why is it wrong to use menyimpan?
