Is there a word which is used to describe the situation when demand for some goods are so high that sellers cannot satisfy it. It usually leads to rapid growth of prices and crowds in shops, even up to fights among buyers, 好像，抢购、轰涌对吗？In Russian, it is ажиотаж.
供不應求 - literally 'supply/not/satisfied/demand'
僧多粥少 - idiom, not enough congee for the monks
It should be "蜂拥”， rather than "轰涌”. And you can call the goods which is very popular "抢手货".
