When joining Lamian Noodles, we need to consider the investment cost and expected income. In terms of investment cost, the specific cost depends on the size of the store and the decoration demand. For example, the equipment and tableware of the 100 square meter basic store will cost about 30,000-40,000 yuan, and 40,000-60,000 yuan will be needed for hard decoration; And the standard store of 200 square meters is correspondingly higher.
