Yesterday (August 8), Hong Kong hair stylist Kelvin Koo was invited to promote a certain fashionable hair brand. As the exclusive hair stylist of the stars like Zhang Bozhi and Gong Li, Kelvin revealed in the interview that not long ago Zhang Bozhi, who had been bothered by the "sex photo scandal", cut off her three thousand烦恼silk (long hair symbolizing worries). She decided to settle down and be a good wife and mother. However, the issue of cutting her son Lucas's hair triggered a war of attrition between her, her husband and her mother-in-law.
