Due to Vietnam's sharing common borders with mainland China's Kwangsi and Yunnan provinces, and the fact that Vietnam was a Chinese suzerainty for a thousand years, the customs of the two countries are similar. The migration of Chinese people to Vietnam also has a long history.
由於越南與中國大陸廣西、雲南省接壤，距離近，又曾為中國藩屬長達千年，風俗習慣類似，華人遷越的歷史相當早。
