Hotel reception systems 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 it can be used for reception operations in Chinese. However, if the hotel reception system software does not support Chinese, then the reception operation cannot be performed in Chinese.

So, 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 a reception system software that does not support Chinese.
