Why can’t the hotel reception system be in Chinese?

The hotel reception system can be in Chinese, depending on whether the reception system software used by the hotel supports Chinese.

If the hotel reception system software supports Chinese, then you can use Chinese for reception operations. However, if the hotel reception system software does not support Chinese, then Chinese reception operations cannot be used.

Therefore, if the hotel reception system cannot be in Chinese, it may be because the system software does not support Chinese or because the hotel has chosen reception system software that does not support Chinese.
