Actually, it's nothing complicated. Most of these competitions are sponsored by named individuals or units. The name of the competition is sometimes named after an individual, and sometimes it is named after the brand name of the company. For example, the famous "Thomas Cup" badminton championship was named after the Englishman George Thomas donated a gold-plated silver trophy to the International Badminton Federation with his own money. Therefore, it was only later that the International Badminton Federation Badminton Championship was changed to a competition called "Thomas Cup". The title of the "Goldlion" Cup Football Invitational Tournament was sponsored by Mr. Ceng Xianzi, the chairman of Hong Kong Goldlion (Far East) Co., Ltd. "Goldlion" is the brand-name trademark of the tie produced by this company.
As for the origin of the name "Double Happiness National 4th Lux Cup Men's and Women's Bodybuilding Invitational Tournament", there is indeed an episode. The first national male and female bodybuilding invitational tournament sponsored by Shanghai Sports Equipment Factory was held in Shanghai. "Lux" is the brand name of the factory's products, so it was named "Lux" Cup, and the factory also sponsored all the bodybuilding invitational competitions since then. The second session was held in Guangzhou, the third session was held in Beijing and the fourth session was held in Shenzhen: Shanghai Sports Equipment Factory sponsored another 6,000 yuan for this Shenzhen competition, but due to lack of funds, the conference later contacted Nanyang Brothers Tobacco Company to sponsor 250,000 Hong Kong dollars with advertisements. The company deals in two famous brands of cigarettes-"Double Happiness" and "Wen Na". After consultation by all parties, the full name of this competition is "Double Happiness National 4th Lux Cup Male and Female Bodybuilding Invitational Tournament".
The same is true for teams named after manufacturers or factory products. For example, the Liaoning Football Team has been renamed as "Liaoning Dongyao Football Team" because it is co-organized with Northeast Pharmaceutical Factory. In this way, in all competitions at home and abroad (except the team name stipulated by the State Sports Commission), the team will participate in the competition under the name of "Dongyao", and the factory will subsidize a certain amount of funds every year for team training, competition subsidies and special expenses. The time to change the team name should be in accordance with the terms of the agreement between the two parties. The purpose of doing this is to encourage the society to run sports and promote the development of mass sports activities. At the same time, corporate sponsorship has also brought vitality to the sports world, or kill two birds with one stone. There are many similar teams that have changed their names in China, such as Tianjin Football Team and Tianjin Watch Factory, and the team name has been changed to "Tianjin Seagull Football Team". In addition, there are Beijing Snowflake Football Team, Guangdong Wanbao Football Team and Baiyun Football Team.
