Currently, the price-earnings ratio is 7.4, and the price-earnings ratio is TTM 5.7. If net profit for the whole year reaches 190 million, then the price-earnings ratio will drop to 4.9 million, but if the depreciation of fixed assets continues to occur repeatedly at a rate of 500 million in 5 years, then net profit will be reduced by 80 million. According to the calculation of 110 million, the corresponding price-earnings ratio is 8.5 million.
