Let me talk about my experience, and ask the landlord for his own reference.

in general, the paper version and electronic version of the tender must be submitted. Paper version of 1 plus n copies (depending on the requirements of the tender documents), and will not be repeated here; Only one electronic version is needed, which can be copied into a USB flash drive or engraved into a CD.

Some bidding activities may require "bidding presentation (or bidding presentation)", and the respondent needs to prepare a presentation, mostly in the format of ".ppt (or'. pptx')", that is, the documents mentioned in the landlord's question.

I bid a lot, and there are no hard and fast rules in the general bidding documents, but I will put it in, and there is nothing wrong with it, right? If the landlord is still very worried, you can refer to the "invalid items" in the "bidding documents" again. If the "invalid items" are not mentioned, you should not worry about anything, right?
