1. Telunsu has invested heavily in TV advertising, and its advertising expenses must be allocated to each box of goods, which is the main reason for the high price.

2. High-quality milk sources will also lead to rising costs. When the wool is on the sheep, the price will naturally go up.

3. According to Mengniu's patent introduction, 1 00g "OMP" milk contains 5.65 ~ 16.8mg IGF- 1 (insulin-like growth factor1). A box of 250ml Telunsu milk contains about 20mg IGF- 1. According to the current market price of IGF- 1 100? G/￥ 580,20 mg = 20,000? G, × 580 = 1 160 (ten thousand yuan), which is incredible.
