Conch and Southern Cement have different reputation and brand awareness in the market. The strength of cement in South China is relatively high, conch is famous and the price is high. This is because the brand awareness of conch is high, so the price is correspondingly high.
This does not mean that the cement in South China is necessarily worse than conch. Southern Cement and Conch are well-known cement brands in China, each with its own advantages and characteristics. Choosing which one is better needs to consider the actual demand and budget.
