Read the full account
On 20 May 2020, after Tsai Ing-wen took the oath for a second presidential term, former premier Lai Ching-te was sworn as vice president, succeeding Chen Chien-jen. A vice president is not co-author of every Tsai statute. The 2024 ticket is a child, not this hour’s unique coefficient.
Context
The January 2020 ticket sat as parent. Neighbouring 2018 premiership had ended. He did not sit as president. COVID sat as parent weather.
2018 Forward-looking is parent premier work. 13 January 2024 presidential win is a child.
The president of the Republic of China (Taiwan) is head of state under the Additional Articles and commander-in-chief. He does not write a PLA communique, a TSMC capex print, or a Legislative Yuan majority. A National Day address is not a completed interceptor. An inaugural line is not a PLA missile. A special-act press conference is not a passed statute. William Lai is a common English name for the same person; the stored English name is Lai Ching-te.
Why it matters
The path is democratic resilience: a completed vice-presidential oath on a re-elected ticket.

Evidence
The sources behind this fact and its verification state.
- 1.Focus Taiwan via Eye On Taiwan — Tsai sworn in; Lai sworn as vice president, 20 May 2020Focus Taiwan (CNA) · High credibility · verified
- 2.Office of the President — 2024 overseas-trip and cross-strait remarks recordOffice of the President ROC (Taiwan) · High credibility · verified
What the sources establish
Office of the President ROC (Taiwan) carries the official instrument or communique. Focus Taiwan (CNA) records the same dated act independently.
Established: 20 May 2020 vice-presidential oath, independently reported.
Not established: a unique later COVID coefficient from that Wednesday, or that he uniquely wrote every second-term statute.
He took the vice-presidential oath. The CEC parent certificate sat.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Lai is sworn as vice president for Tsai’s second term, not a later speech about Lai is sworn as vice president for Tsai’s second term.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Tsai was principal. He took the vice-presidential oath. The CEC parent certificate sat. That limit is the alternative to treating office-holding as authorship of every later series.
