How to make welcoming couplets at the inauguration ceremony of ancestral temple?

Re-adjust according to the original intention and try to draft a couplet:

Celebrate the National Day Mid-Autumn Festival and the completion of Zonghe Temple.

Welcome leading guests and relatives to visit.

Note: The basic meaning of "auspicious" is "harmony", "harmony" and "harmony", so that the National Day, Mid-Autumn Festival and Shanglian Ancestral Hall are completed side by side. According to the order of officials and people, the upper and lower nouns correspond, the official National Day comes first, the folk custom comes later, and the family affairs comes last; Leading guests must go out to meet, and relatives only need to wait; Because of the use of relatives and friends, the official language "Lai" is not appropriate. "Lai" is both official and private. In addition, clan relatives and clan relatives have similar meanings in a broad sense, which can avoid the repetition of words.

I hope my answer will satisfy you.
