Mandy Wei

In 2016, Wei played the lead in Sanlih Friday night drama, Swimming Battle, alongside Kingone Wang. Wei played "He Yu Die" (何雨鰈), a woman who lost her memories.

In mid 2015, Wei once again collaborated with Sanlih by starring in a romantic comedy opposite Jasper Liu. Wei played "An Xi" (安希), a caring and independent woman who cannot stand injustice. Since Wei's hair had not grown out since Say Again Yes I Do concluded filming, she had to wear hair extensions to obtain a more youthful appearance since she had flash back scenes when her character was a university student.

With the success of Deja Vu Sanlih offered Wei another leading role in their 2014 Sunday night drama Say Again Yes I Do (再說一次我願意), playing "Shu Xin Kui" (舒芯葵), a women who marries a man she just met on a whelmed, played by Lin Yo Wei, only to find out she can't stand him and divorces him abruptly only to meet him a few years later and falls in love with him again. For this drama Wei decided to change her look by drastically cutting off her long hair to a near pixie cut. Her appearance was a drastic change from her previous projects, but the drama was another rating success, coming in first place in every episode during its time-slot.

Her big break came in 2012 when she was cast as "Dr. He Cai Rong" (何采蓉) in SETTV's weekly hit drama Love, Now (真愛趁現在). Originally a minor supporting character, her chemistry with second male lead Bobby Dou (竇智孔) proved to be a winning combination and soon her role was expanded to a main supporting role.

In 2008, MTV Taiwan offered Wei a VJ position to host their entertainment news program and music program "MTV FUN Music" (MTV FUN音樂) where she interviewed local musical acts. In 2012 Wei became the host for entertainment gossip news website Apply Daily Taiwan.

Wei got her start in acting as a supporting character in the 2008 idol drama ToGetHer (愛就宅一起), playing "Luo Sha Sha" (羅莎莎), the leader of a University mean girls cliche, who picks on a homely girl played by Rainie Yang and is a huge fan of a celebrity idol Mars, played by Jiro Wang. She spent the next few years playing supporting characters in sometimes forgettable dramas and other times more popular dramas such as 2011 Material Queen (拜金女王).

Wei started her career in 2006 as a lingerie and swimwear model. She had modeled for lingerie brand NuBra Taiwan and appeared on spreads for FHM Taiwan and GQ Taiwan magazine. After gaining exposure through her modeling work she was chosen to appear in Jay Chou's 2008 music video Snake Dance (蛇舞).

Mandy Wei was born on September 5, 1984 in Taipei, Taiwan. She is the older of a two-child family, with a younger brother. She attended Taipei Municipal Neihu Senior High School and later Soochow University, majoring in International Business Trade. She has said she was, and showed images of herself being an overweight teen when growing up, weighing at 65 kg (143 lbs) at her heaviest. Her weight issue caused her to have low self-esteem problems during her teenage years. In her university years she decided to have a change in lifestyle by eating healthy and with daily exercise she was able to slim down to around 50 kg (110 lbs), which is the weight she has maintained.
