How to treat this way of emphasizing production and neglecting marketing?

Pay more attention to production than marketing. In my opinion, this is a strategy to win by products.

If the emphasis is on quality, it will be spread by others as long as it is promoted a little. I don't think it's too far to say that heavy production is not far in quantity. If mass production costs a lot of effort, then sell at a low price and adopt the strategy of winning by price, which is cheaper than you. I won't mess with you. It's cheaper than you.
