Hou studied in the United States, majoring in tanning, and made his mark in the tanning industry. That doctoral thesis was highly praised by his tutor. Now he wants to give up tanning and start a new stove, specializing in alkali production. At first, he hesitated. When he learned that the capitalist countries monopolized the alkali-making industry in China, profiteering, and the people had no alkali, he made up his mind to win a sigh of relief for the people of China and produce soda ash from China, so he accepted the invitation of Wynn Alkali-making Company without hesitation and set foot on his way home.
