South What in Chinese / Japanese...

詠春拳 is the title for the “Wing Chun” school of martial arts but with the addition of the character for “fist” at the end. So this is “Wing Chun Fist” or literally “Singing Spring Fist.”

There are lots of alternate Cantonese romanizations for this, such as “Wing Chun Kuen,” “Wing Tsun Cheun,” “Eng Chun Pai,” and “Wing Ceon Kyun.” The characters are the same; just the lack of a standard Cantonese romanization means that people make up their own based on what they think it sounds like.

跆拳道精神禮義廉耻忍耐克己百折不屈 is General Choi's writing that is often called “The Tenets of Taekwon-do.”

The actual title would be translated as “Taekwondo Spirit” or “The Spirit of Taekwondo.” It was originally written in Korean Hanja (Chinese characters used in Korea for about 1600 years).

身土不二 (Shindofuni) is originally a Buddhist concept or proverb referring to the inseparability of body-mind and geographical circumstances.

This reads, “Body [and] earth [are] not two.”

Other translations or matching ideas include:
Body and land are one.
Body and earth can not be separated.
Body earth sensory curation.
You are what you eat.
Indivisibility of the body and the land (because the body is made from food and food is made from the land).

Going further, this speaks of our human bodies and the land from which we get our food being closely connected. This phrase is often used when talking about natural and organic vegetables coming directly from the farm to provide the healthiest foods in Japan.

Character notes: 身(shin) in this context does not just mean your physical body but a concept including both body and mind.
土 (do) refers to the soil, earth, clay, land, or in some cases, locality. It's not the proper name of Earth, the planet. However, it can refer to the land or realm we live in.

Japanese note: This has been used in Japan, on and off, since 1907 as a slogan for a governmental healthy eating campaign (usually pronounced as shindofuji instead of the original shindofuni in this context). It may have been hijacked from Buddhism for this propaganda purpose, but at least this is “healthy propaganda.”

Korean note: The phrase 身土不二 was in use by 1610 A.D. in Korea, where it can be found in an early medical journal.
In modern South Korea, it's written in Hangul as 신토불이. Korea used Chinese characters (same source as Japanese Kanji) as their only written standard form of the language until about a hundred years ago. Therefore, many Koreans will recognize this as a native phrase and concept.
