Answer 1

\b only works on boundary between words and non-words. In case of Chinese, the entire '你说到这是一个测试' is considered a word, so '一个' won't match '你说到这是一个测试' with your regex pattern with \b since '一个' is not at the word boundary of '你说到这是一个测试'. '测试' on the other hand, will match. For Chinese words, a simple substring match is usually enough.
