Lei Lutai / 雷履泰

Lei Lutai is the piaohao manager associated with Rishengchang / 日升昌 in No.209 晋商往事：走西口到乔家大院然后煤了. The episode credits him with seeing that a merchant shop’s internal remittance mechanism could become an external business, helping turn the former Xiyucheng pigment shop into the Rishengchang piaohao.

The source uses Lei as the personification of Shanxi Piaohao innovation, but not as a lone-founder myth. Mao Honghui / 毛红汇 is presented as another important early participant, and the later Lei-Mao conflict is used to explain how rivalry helped spread the piaohao model across competing firms.

Key Claims

• Lei’s importance lies in converting an internal settlement convenience into a scalable public remittance service.
• The source connects Lei to operational trust: drafts, branch letters, codebooks, handwriting, seals, and silver-quality conversion all had to work together.
• His conflict with Mao Honghui is framed as both organizational friction and industry diffusion.

Connections

• Rishengchang / 日升昌 and Shanxi Piaohao — institution and category Lei is tied to.
• Mao Honghui / 毛红汇 — rival/counterpart in the episode’s early piaohao story.
• Long-Distance Trade Friction — problem the piaohao model addressed.
• Jin Merchant Governance — management and incentive context for Shanxi merchant houses.
