The use of the anthem in the Macau Special Administrative Region is particularly governed by Law No.5/1999, which was enacted on 20 December 1999. Article 7 of the law requires that the anthem be accurately performed pursuant to the sheet music in its Appendix 4 and prohibits the lyrics from being altered. Under Article 9, willful alteration of the music or lyrics is criminally punishable by imprisonment of up to two years or up to 360 day-fines[37][38] and, although both Chinese and Portuguese are official languages of the region, the provided sheet music has its lyrics only in Chinese. Mainland China has also passed a similar law in 2017.
