Zhou Xun and Denise Ho pose for a picture.

Chinese actress Zhou Xun joined Hong Kong singers Anthony Wong and Denise Ho in shooting a series of posters to promote the book "All4love" by "BigLove Alliance". Hong Kong actor Anthony Wong Chau Sang also stars in the campaign.

In one of the images, Zhou's shoulders are decorated with colorful stickers, while the "word" love is stuck to the corner of Ho's mouth. The faces of the two stars are positioned so that they appear to be almost kissing. Anthony Wong Chau Sang and Anthony Wong feature in a separate photo on the same poster, bearing the first and last two letters for the word "love" written on their faces.

Ho wrote on her Sina Weibo microblog on Tuesday that the aim of "All4love" was to promote the concept of equal love, adding that no matter whether you share different-sex love or same-sex love, we all live under the same sky. She expressed her thanks to Zhou and Wong and Wong Chau Sang for their support at the end of her post.
