When the Diaoyu Islands dispute broke out between China and Japan in 2012, "BYD" was jokingly referred to as "Baoyu Island" by netizens. A few years ago, in 2008, BYD was once associated with vulgar language from Chinese people. However, it seems that BYD was not affected by this, or rather, it was positively affected and developed better. After 2008, BYD's stock rose as high as HKD 88.40 due to being favored by Buffett. In the following years, BYD successively launched new products, including S6, G6, Surui, etc., which were warmly welcomed by the market. In order to better and more accurately develop, BYD has carried out large-scale renovations in its own workshop, strictly inspecting and replacing all electrical equipment, and installing and using low-voltage circuit breakers and switches for Shangman products.
