Tavia Yeung was asked about the state of her love life, and her non-answer had a lie detector machine go off the charts.Yesterday Tavia Yeung, Aimee Chan, Christine Kuo, Edwin Siu, Matthew Ko and the rest of the cast of TVB series A Great Way to Care II attended a promotional event. The event organizer had hired a psychiatrist to assist in the games, who brought a lie detector with him and tested it on Tavia, Aimee and Christine. When Ronald Law asked Tavia how she's currently doing in her love life? Tavia changed the subject: "I have outdoor shooting later." The lie detector readings were highly unstable, leading the psychiatrist to conclude that Tavia was feeling extremely uncomfortable.When Aimee was asked whether she has an especially good feeling for anyone by the surname of Chan? She didn't know how to answer either and just smiled. The test results indicated that Aimee's heart was beating very fast, leading the others to tease that it was because she had drunk too much coffee.
