Bian Boxian's album sold 880,000 copies. Chinese fans bought about 700,000 copies. Why didn't he write in Chinese when he signed the sale? The answer to this question might involve some business and marketing strategy factors. As a singer, Bian Boxian had a large fan base in the Chinese market, and his album sales in China were relatively high. Therefore, the reasons why he did not write in Chinese during the signing event might be as follows: Business strategy: Bian Boxian and his company may think that using Chinese as part of the signing event may increase the number of his Chinese fans and thus increase their sales and profits. However, as a Korean artist, his Chinese level might be limited and he might not be able to fully understand the needs and feedback of his Chinese fans. Therefore, he might choose not to write in Chinese. 2. Cultural differences: China and Korea have great differences in culture, language, and values. Bian Boxian probably thought that not writing in Chinese at his signing event could reduce his cultural shock, protect his privacy and self-esteem, and also reduce the communication barriers between him and his Chinese fans. 3. Marketing strategy: Bian Boxian and his company may think that attracting Chinese fans by not writing in Chinese is a relatively new marketing strategy to attract more young people to pay attention to their music. At the same time, Byeon and his company might also use his Korean background and the emotional connection between his Chinese fans to increase their sales and popularity. Bian Boxian did not write Chinese in his signing event because of business, cultural differences, and marketing strategies.
