School of Basic Medical Sciences launched the monthly Birthday Party in 2009, from when it has become one of the traditions of School’ culture. Every Friday evening of the last week of each month, the dance instructors from Wenqin Art Troupe in Zhejiang University are invited to lead the postgraduates whose birthdays are on that month to dance, including Waltz, Tango, rumba, Cha Cha Cha and so on. It is so relaxing that all worries and troubles are left behind.
